Unfortunately that doesn't account for the auto-install tracking 
aptitude uses, since it's a higher layer than dpkg.  But there are ways 
to recover that, especially with *buntu where most things are 
auto-installed.  But I'm not sure you need anything but the 
manual-installed list.

I think that tells apt-get to use the selections another tool has made. 
  If you do dpkg --set-selections you'll see those selections in 
aptitude or dselect or whatever.

Using apt-get to install what dselect has selected is different than 
using apt-get to resolve dependencies for you.  The tools have always 
seemed to me somewhat fragmented in that regard.
