I don’t (at least not in the way it is expressed). If
you want to use
the page title as a tiebreaker, then add it as a new column to the
index (before the page_id), not (as I read the original sentence) by
appending the title to the sort key.
The page title is not in the categorylinks table, so we can't add it
to the index.
Otherwise, you’ll have to separate the sort key from
the title with
some control character under U+0020 (to ensure correct ordering of
different-length sort keys – you need a separator which sorts before
any valid character), which would be messy.
But still, I don’t see the point in doing that. You don’t want a page
called “Aaa” to come after a page called “Abc” when you set their
sortkeys both to the same value? Don’t do that then. Set the sortkey
accordingly to what you want.
Exactly. When using identical sortkeys, you shouldn't complain that
MediaWiki doesn't magically know in which order you want to sort them.
You can make it predictable by using a (more) unique sortkey.
