Are you talking about the order that the achievements are shown on the screen bobcachievements? They should be shown in the order they were defined in BOBCACHIEVEMENT_LIST if you're running Ren'Py 8.1, but if they're not, there's a possibility I misunderstood something about dict ordering.
If you're sure you're on Ren'Py 8.1, try changing line 57 of sbobcachievements.rpy from:
for achievement_id in BOBCACHIEVEMENTS_MAP:
to these two lines (with appropriate indentation before the second line):
for aid in BOBCACHIEVEMENT_LIST:
$ achievement_id = aid[0]
