It's not supposed to, judging by the wording of it, but it does. The 1-50 achievement will not pop until you get a score on a floor after 50, and similarly the one for clearing to 100 won't until you get a score on 101 or later.
A friend suggested contacting support in game about it if it happens to have them force it to trigger, but my experience with that has been essentially "Well maybe you should talk to Jonathas for your title?" and then "Sorry to hear that, not helping. Go file a bug report." when repeating that the complaint wasn't about the title but the achievements themselves not happening properly.
