You don't need to write a script for this: there are existing tools to help
with it.  You need maildircmd and safecat [1], both written by Len Budney.

Here's how I have solved a similar problem:

1. Deliver your mail to a temporary Maildir. Let's call it Maildir/spool
2. Then run maildircmd on Maildir/spool and feed the results to safecat, which
delivers the filtered mail to your inbox, say Maildir/inbox.

  maildircmd Maildir/spool "" "bogofilter $bogofilter_options| \
    safecat Maildir/inbox/tmp Maildir/inbox/new

Ideally, you would want to filter your mail into separate mailboxes.
That's where procmail or mailfilter come in.
