The following should fix it:

zstyle ':completion:all-matches:*' insert true

This is mentioned in the manual under the style "insert", but you have
to go hunting and have some idea of what you're looking for (I actually
found it by looking at the completer itself.)  The business about the
completer doesn't seemed to be mentioned at all, but I have the same
experience as you.  It looks like the manual needs to be updated.

I haven't tried this, but you *should* still be able to use the
tag-order style with all-matches.  The context will be different,
though; as in the styles you quoted it should start
':completion:all-matches:'.  If it's not that obvious or nothing works,
let us know.
