If we allow authors to edit a content of the UMOs they found in
Repository, we can allow them to decide to what level of difficulty of
their course the found UMO will belong.
Regarding your two-part difficulty idea. It makes sense to me, the only
problem imho is that it's not that obvious and will require additional
explanations to users. Maybe use just one number? Say, community votes a
problem block as difficult as "3". An author designates it as the most
easy to solve, and decide whether he wants to downgrade it to lower level
or leave it as it is. If yes, he assigns smaller single number to it.

Author will be able to reassign object from one difficulty level to
another within his Course if he changes his mind or, for example, students
give this object poor rating with difficulty related complaints.
