I have had about a 90% success rate with Yahoo for months. However, recently, I have submitted sites I "Knew" were going to be accepted, but they weren't. Something has apparently changed, possibly as a result of the new affiliation, maybe department turnover, etc. My guess (write this down kids) is that they are going to start selling these listings in some as yet unaaanounced way, and are in the process of jacking up the Market!
