Dunno about procmail, but it's easy to resort with maildrop:

  reformail -s maildrop < mbox_file

will cause the whole mbox_file to be broken into individual
messages that are then (re)processed by your current maildrop
configuration (using your current .mailfilter). The reformail program
comes with maildrop; see the man page.
