Maybe there's some way of abusing the "send-to-omnifocus@omnigroup.com" email thing?
If you forwarded each email that you wanted to turn into a task to there, and had a smart folder set up in mail that would nab anything coming from that address.......
Then I'm lost, but I'm pretty sure there must be a way to get text expander (it'll handle scripts) or quicksilver to scrape whatever's in that folder into omnifocus. Maybe. Not enough of a ninja to work out what last step is between folder and profit though
