This is a documented limitation, or at least it should be documented.  :)

Tasks can't read discrete values because a task step cannot be 
"undone".  This is why they are only run from the system event 
loop.  If you need to communicate discrete events to a task, you will 
need to write them to a list or something of that sort, and then have 
the task read and remove them.
