It's a bit difficult to exactly describe the behavior of the stalled filter in the applescript language because there are some missing pieces!

Try coming up with a query that shows just those projects treated as dropped because they are in a folder which is marked dropped, the project otherwise being active. The stalled filter will not show these.

If you solve that, then come up with a query for projects which have no available actions but do have future actions (number of tasks - number of completed tasks > 0). I didn't succeed in getting such an expression through your script, but I didn't spend much time at it.

I think what the stalled filter gives you is this:

projects where (completed is false) and ((status is not dropped) and (not contained in dropped folder)) and (status is not on hold) and (status is not pending) and (number of available tasks is 0) and (number of remaining tasks > 0)

The first 5 clauses (through "not pending") collect the subset of projects yielded by the position of Stalled in the sidebar filter: remaining - on hold - pending. The remaining 2 clauses are the meat: which projects are stuck because I can't work any of their actions?
