By the way, does this handle races during the disguise phase? I am an Argonian in-game, how can I wear Imperial Armor and pretend to be a guard, when all guards are men (and most probably Imperial as well)??
It certainly does take race into account (not gender though, don't want to be unnecessarily sixist).
An person playing an Imperial character will need to wear a Cuirass, some Greaves, and a pair of Boots to be disguised. These can be townguard cuirass', with chainmail greaves and boots, standard Legion equipment, or anything in between. Once they are wearing those items other NPCs will begin to treat you like a guard.
However in the case of your Argonian character the NPCs would immidiately notice that you are not human (unless they are blind... come ot think of it I once got into a fight with some blind priests and they kicked my butt). Therefore the mod requires Argonians, and races like them - Kajiits and Orcs, to wear gauntlets and helmets as well as the cuirass, greaves and boots that the Imperials have to wear. So as you can see, it makes sense that if your face is covered and they cannot see any other part of your scaly body they assume that you are human.
List of Disguise Requirements:
