Though my calucations result into different numbers, did I miss something?:

Scaling part of Rake - Spell - World of Warcraft AP * 0.18

Enchant 2H Weapon - Scourgebane - Spell - World of Warcraft scaling with Predatory Strikes - Spell - World of Warcraft: 140 AP * 1.1 * 1.2 = 184.8 AP
Enchant 2H Weapon - Scourgebane - Spell - World of Warcraft not scaling with Predatory Strikes - Spell - World of Warcraft: 140 * 1.1 = 154 AP
Difference: 30.8 AP

Resulting Rake DMG per tick difference Undead vs non-Undead mob: 30.8 * 0.18 * 1.1 * 1.04 = 5.54400 DMG.

Edit: Master Shapeshifter - Spell - World of Warcraft does affect Rake ticks? What about Naturalist - Spell - World of Warcraft then?

If both affect Rake ticks, then the resulting Rake DMG per tick difference Undead vs non-Undead mob: 30.8 * 0.18 * 1.1 * 1.04 = 6.342336 DMG.

p.s. Wowhead says the DoT scaling of Rake is AP * 0.18. The AP scaling works against the whole spell not each tick? (3 ticks each 0.06 AP)? If that is the case, with my numbers the difference is rather 30.8 * 0.06 * 1.1 * 1.04 = 2.114112 DMG

Edit 2: NVM now it fits with your calcuations. (if Naturalist doesn't scale Rake ticks, its 30.8 * 0.06 * 1.04 = 1.92192)
