Lua string comparisons are O(1); in fact, inside the scripting engine, they are a simple pointer comparison, as equal string values are guaranteed to be at the same place in the string pool.

That said, I agree they're likely doing something special with unit IDs, and wouldn't expect this function to work on random strings (although my armchair guess is that, given the way string "interning" works, it wouldn't be Too Difficult to make it work...).
