I would assume it does, however if a boss is immune to something like "Curse of Tongues", he'll probably be immune to the deathfrost effect as well. The effect is marked as physical however, so it should (in theory) persist trough the shields at the illidari council and may have a use there for the rogue helping with interrupts.
Another thing, worth investigating, is whether is procs on direct damage (spells) only, or also aoe such as arcane explosion / consecration. And, if the enchant has two components like Sapphidia stated, whether it can proc off a rogue's instant poison. (unlikely though as blizzard fixed double triggers)
Other than on trash however, i fail to see the utility of the enchant other than for pvp. Both thunderclap, mind numbing poison and curse of tongues are clearly superior as individual debuffs in pve raids and with an 8 second duration it's also fairly short compared to the other debuffs.
