Creating a plugin with dynamic scoring

[Larry Nedry]

Hello,

I'm developing a plugin that adds a dynamic rule score to the SA 
calculated score. It works well except when the SA calculated score is 
less than the required_score and the final score is greater that the 
required_score. In this case the X-Spam-Status header always shows "No, 
score=4.9..." and the X-Spam-Report header doesn't get written. If the 
_SCORE_ is displayed in the subject, it shows the correct score.

Here's the trimmed version of the relevant code:

sub check_end() {
    my ( $self, $params ) = @_;
    my $pms = $params->{permsgstatus};

    my $sa_score = $pms->get_score();
    $foo_score = sprintf("%0.3f", $sa_score * 0.10);

    my $required_score = $pms->get_required_score();
    if($sa_score > ($required_score - $foo_score)) {
        $pms->got_hit('FOO', '', score => $foo_score);
    }

    return 0;
}

Is there a better way to update the SA score?

Regards,
Larry
