I don't think that's the issue at all. It is a matter of being able to say that you did it "The Standard Way" (i.e. their way, by the book/manual) or not. It really doesn't matter how trivial the procedure is, or even whether it is the right thing to do. Even if you do a complete clean-room implementation of their scoring system, they can claim either that what you do is not SF-36 or if you say that it is, that you owe them money.
