Dave,

Have you look at the OF Extras forum? That's the home for Applescripting OmniFocus. You'll find links to a bunch of scripts there. My Complete and Await Reply script (available from my software page) does some of what you're looking for. It mucks with contexts and dates, so it might serve as a starting point.

It will be easier if you just process the tasks in place, then use the Clean Up command to get them out of the inbox. Clean Up can be called from a script.
