This looks good, and I think you should try it.

One concern is that even if we split source_file up into multiple  
fields later, we still end up having to support this format for old  
set definition files. Probably not a big deal.

Another issue is not having a one-to-one correspondence between  
problems in the "prototype" UserSet and problems in the versioned  
UserSet. If that seems like a problem then the second solution would  
probably be better.

Speaking of which, I don't think option 2 would be that hard to  
implement. assignSetVersionToUser could keep a hash and pass it by  
reference to assignProblemToUserSetVersion, which would record the  
actual source files chosen for each group and check the existing  
entries to rule out duplicates.
