Looks like you found it! All the milestone messages (PMSGMSPS.INI) are priority 1, so I bet that's just which message plays if multiple are triggered. It looks like each milestone has ten messages, with one randomly selected, judging by that file's comments. No comments in the file for general messages, but my guess is that either they're heavily random or that they're influenced by what games you play, how much, and/or what level. Interesting...
