Here's how we do it here (we don't alter the Subject: line though):

# If SpamAssassin found SPAM, append report.  We do it as a separate
# attachment of type text/plain
sub filter_end ($) {
[...]
    # Spam checks if SpamAssassin is installed
    if ($Features{"SpamAssassin"}) {
[...]
        # Delete any existing X-Spam-* headers
        action_delete_all_headers("X-Spam-Score");
        # We don't set X-Spam-Level but outsiders sometimes do:
        action_delete_all_headers("X-Spam-Level");
        action_delete_all_headers("X-Spam-Warning");
        action_delete_all_headers("X-Spam-Checked");
[...]
        my($hits, $req, $names, $report) = spam_assassin_check();
