My experience with MSN lead me to believe that there are 2 seperate database. I chose a particular keyword that is pretty competitive but not extremely, and memorized the top 10 results. I always saw 2 different sets of results. When it was on one set, people were happy. When it was on the other sets, webmasterworld was filled with hair and tears. And people called the bad sets as the "old" database and the good one as the "new" database.
