You have to understand that I'm coming at this from a developer's perspective. But since you asked, here are a few arguments against using a calendar picker: The interface would no longer be using the standard iPhone date picker that every iPhone user is already familiar with. It might lead to confusion due to someone thinking that there was an actual calendar built into Action Lists. The calendar I would use would be someone else's code and might have bugs that I can't fix. The calendar might have code in it that might cause the app to be rejected from the App Store at some indeterminate point in the future (eg. Three20's recent problems).
All that being said, my current inclination is that a calendar-based date picker would be a a big enough benefit to overcome the downsides. But as I said before, I still haven't taken a really close look at how I could implement it.
