FYI in pathfinder both robes and armor take up the same slot. =)
To my knowledge, it is different slots. Armor being the armor slot, a robe being the body slot.
Since the Sohei Monk does not have the abilities granted by the Monks Robe, I would rule that he get the increased unarmed damage as a non-monk.

So if a Sohei wears a monk's robe, does he get any bonus off it?
The Sohei is a monk but he doesn't get increased unarmed damage.He wears armor so he doesn't get the AC bonus.
He doesn't have stunning fist, so again no bonus.
Or would he get increased unarmed damage as if he wasn't a monk?
He doesn't have to wear armor so he could get the AC bonus. He can take Stunning Fist feat.

Sorry to disappoint, but the guy who actually wrote the archetype chipped in on a thread where it was discussed and clarified his intent of not being able to flurry while in armor. Kinda strange, but he felt it would be a little too good or something along those lines. If I wasn't too lazy I'd find the post for you, but... yeah. :P
