I wondered that too. But I think the explanation is that the Room of 
Requirement *creates* nothing. It brings things from other places.

In which case, the parchment would be genuine - whether it was 
originally in the room or not, there had to have existed a piece of 
parchment headed 'Dumbledore's Army', with all the member's 
signatures. Otherwise it couldn't be in the room at all.

So it's still evidence. The Room of Requirement was simply helpfully 
collecting it for the Inquisitorial Squad.
