I believe you should use the highest number of the rules, not the lowest. In Karmic I had rules with 45-*.rules and 70-*.rules. When I created a 45-wminput.rules nothing changed, but using 70-wminput.rules fixed the problem.
But now, I'm on Lucid and I just have one rule before adding wminput, so I can't really tell if that works on Lucid.
