Ah-ha!  Now, that makes sense.  
I observed the same problem on our system (just now--I had not previously tested that checkpoint defaults were related to my non-login shell issue).  I had previously seen that cluster jobs would not run in a "login shell", except when running them interactively.  You can read my correspondence with (the very helpful) torque-dev list here:

That helps a lot to narrow it down perhaps.  I will re-file my bug report with the updated symptom:
