Actually I re-read your problem. Sham links may be a solution to look at, if you control the right pieces of equipment. You can also mess with the AD of OSPF external routes versus OSPF internal routes but this is probably a Bad Idea(TM) (and my testing of this a few years ago showed it didn't have the desired result).
