I saw your subject line and went "oh, I bet I know at least a bit about one of them," but, nope, you've stumped me. :P
Tony would either pick it up really fast (and be slightly miffed that JARVIS kept a secret from him) or be completely in denial about the whole thing forever. Probably option one! (I guess it's possible that JARVIS told him right after he took the Oath and they went and did some research together, actually.
...oooh, I wonder if JARVIS's Ordeal was while Tony was captive with the Ten Rings...)
