SpamAssassin & Sieve?

[+archive . info-cyrus]

I guess slightly off-topic, but I was wondering if any folks on here are using SpamAssassin, and if so, what sort of Sieve scripts you're using on such tagged mail. I know that recent releases of Sieve have a numeric comparator. Are you using that somehow, or just a simple match on the "X-Spam-Level: ***" header?
