Whoever is first wins.  This is a problem in all approaches discussed
thus far.  You can't have two plugins trying to replace core functions.

Filename ordering works well enough for SysVInit.  S01, S02, S99, ...

Once upon a time, Morgan and I discussed having a Priority: field and
changing the active_plugins array to have priority levels, much like
wp_filters.

I haven't cared enough to bother with it though.  Just naming the plugin
01-do-me-first.php has worked well enough.
