I already know that some exam questions were not created in that order, so that would not work as a general solution (I should have thought of that, we could have accommodated that though).

I'm starting to think that having them renamed into 01, 02, ... isn't such a bad thing and is fairly easy to implement in the few exams that require it. I won't implement that for another few days though, so if you come up with another idea, let me know!

Cheers,
