For all users the title with the lowest count is returned

In user_titles.module the sorting in user_titles_get_titles() is broken. It was OK in rev 1.15.2.1 and got broken in 1.15.2.2.
Line 646 changed from $query = db_query("SELECT title, value, tid FROM {user_titles} ORDER BY value DESC"); to $query = db_query("SELECT * FROM {user_titles} ORDER BY value");
Note the missing sort order specification ("DESC").

Thats why user_titles_get_title() always returns the title with the lowest value.

HTH,
