My approach with "weights" is to answer the question, "If someone gave you 1 item point, what would you want it to be?" Right now, the answer is 1 Str (weight 1.1). If you couldn't get that, you'd want either 1 CR or 1 Agi (weight 1) or 2 AP (weight 0.5). If you couldn't get those, you'd say 1 HR (weight 0.7).
Where does INT fit in there? I'll do a super rough calc that perhaps other people could refine.
1 INT = 15 mana.
Converting mana into damage: ES spam is 675 dmg / 535 mana, or 1.26 DPM. (Not accounting for FS/ES rotations or SS debuff, rough numbers.)
So the 1 INT gives 15 * 1.1 (kings) * 1.26 = 21 damage. Generously, we can say that you get to reuse it every 2 minutes because of SR, making this 21/120 = 0.18 dps.
(I'm overlooking the ES cooldown, because the max number of shocks in a 2 min window is controlled by mana, not by that cooldown.)
Tornhoof's sim and my sim agreed earlier this week that 100 AP would add about 22 dps (to someone with approx. full kara gear). That's 0.22 DPS/AP, compared to 0.18 DPS/INT. Ratioing down from AP's weight, the weight for INT should be about 0.5 * 18/22 = 0.41.
These are really rough numbers and there might be errors. But if they're approximately right, INT is so weak that you'd prefer even 1 point of AP to 1 point of INT.

Not including CoE, imp. scorch, Misery or SS debuff is a mistake imho, ES+FS rotation is ~156 DPS. According to the
simple maths I did comparing Bladed Shoulderpads of the Merciless vs Cyclone Spaulders, if you accept that it is possible to run OoM, there's definitely cases where going for the int is more advantageous.
I suppose creating a ratio isn't as useful as other stats, as after your mana pool is a certain size compared to your gains from SR, it stops contributing to your DPS. The fact that the question "how much int do I need" will vary for different encounters, your stats, and raid composition. With no gear changes, on one week of Gruul, I gained
3-4k mana per Shamanistic Rage. This week, with a Survival Hunter and two Warriors in my group (meaning I get Battle Shout for the entire fight rather than just the first half), I gained
7.5k mana.

What's the maximum mana pool required for 2 minutes of SS, ES/FS, and totems between Shamanistic Rage (plus mana pot) cooldowns?
I think someone has done this work before, but it's easier for me to duplicate it than to search for it.
SS x 120/10 = 236*12 = 2832
SoE, WF, Mana Spring x 1 + Searing x 2 = 225 + 243 + 90 + 153*2 = 864 (note this is with Totemic Focus, adjust upwards by 25% if this doesn't apply to you... now that I explicitly see that this talent is only worth 288 mana/120 sec = 12mp5, I might get rid of it)
Mana gained from Mana Spring = 12*120/2 = -720
ES x 120/6/2, minus one lost to GCD = 535*9 = 4815
FS x 120/6/2, minus one lost to GCD = 500*9 = 4500
Totemic call with 5 seconds left on totem durations = -238
2832 + 864 - 720 + 4815 + 4500 - 238 = 12053
We can then safely say that any INT which raises our buffed mana pool above 12053 is going to be useless, if we can get a refill off of SR + mana pot. If one waited until their mana pool were depleted by the amount of a Super Mana Pot at the start of a fight, chugged one, and then continued chugging each time the CD was up, you would get a larger "effective" mana pool without any more INT. A Super Mana is at least 1800 and averages 2400 mana, so if you accept the average, you don't need INT which raises the buffed mana pool above 9653. (Do pots still crit?)

They can, but generally, Fel Mana Potions are a better bet (3.2k mana restored).
Also, don't forget that Bloodlust is 750 mana. Obviously, you don't cast it ever 2 minutes, it needs to be considered.

Obviously, this is going to vary a lot with gear; and as most shamans know, it also depends on the fight (whether or not you can get a nice solid 30 seconds of attacking the ass end of a boss mob without having to move). We know that you get 15% of your AP back per proc. Do we have hard data on whether this is PPM or percentage-based?

I use WWS to give me an indication of how much mana will be restored in a given encounter. I believe it is PPM.
All this theorycraft is irritating though. Surely with all the high-end raiders we have posting here, some would have a heavy leather gear setups they can post experience about using?
