Michael and I talked about this on IRC, and it seemed that changing tasksel to use apt-get would be the path of least resistance for now.
However, I just had a look at tasksel and I can only do this by dropping a feature (installation by priority). That may not matter too much in the Ubuntu case, but if I can avoid dropping features then that would be preferable - so if fixing aptitude so that its task installation plays well with apt's auto-marking is easy, then that would be best.
