Right, I don't have the code in front of me right now, but I think your issue is at the "aggregation" point. You also have to put some code in the aggregation bits that pull your custom parts from the sub-request packets and puts in the final packet, "doing the right thing" in terms of assembling them into something meaningful along the way (e.g. averaging "myvar" or putting it in a list identified by shard or......).
I think if you fire the query at one of your shards with &distrib=false you'll see your additions, which would demonstrate that your filter is being found. I assume your custom jar is on the shards or you'd get an exception (assuming you've pushed your solrconfig to ZK).
