To clarify, here's the information that's available when sorting a category membership list:
- category name (fixed, since we're looking at a particular category)
- sort key (normally the page title, unless you overrode it)
- page ID (roughly corresponds to page creation time)
The page title can only be applied to the sorting if it's actually *in* the sort key. If you've overridden it, then *only* the sort key you provided will have any relevance in ordering; page ID will serve as a 'tiebreaker' but isn't really predictable.
We could break ties by appending the page title to custom sort keys, if this is a problem.
