Deleting the existing X-Spam-Score tags will also help, and may be an even 
more reliable solution since you don't have to be concerned that 
possibly-malformed X-Spam-Score tags might be doing bad things with your 
code.

I delete all of the incoming tags that might be used by downstream users to 
make use of the classifications that the local MIMEDefang process might add:

        action_delete_all_headers("X-Scanned-By");
        action_delete_all_headers("X-Spam-Warning");
        action_delete_all_headers("X-Spam-Status");
        action_delete_all_headers("X-Spam-Report");
        action_delete_all_headers("X-Spam-Score");

That said, your insheader patch can still be useful for other situations so 
don't give up on it!
