The solution I ultimately found was to set
export PYTHONHOME=/usr/autodesk/maya2013-x64
within maya's os.system() call before the external python script is executed, then within the script un-set it or set it back to /usr/ before the rest of the imports are executed. None of the PYTHONPATH related solutions worked.

Oops, forgot to add a line that /changes/ the PYTHONPATH to
whatever you want PYTHONPATH to be when your_cmd is running.
Also, it might be best to make that code a bit more robust,
protecting it from a situation where PYTHONPATH /isn't/ set, e.g.
# SAVE OLD PYTHONPATH
if os.environ.has_key("PYTHONPATH"): ppsave = os.environ["PYTHONPATH"]
else: ppsave = None
# CHANGE TO WHAT OS WANTS
os.environ["PYTHONPATH"] = "/what/you/want"
# INVOKE UNIX COMMAND
os.system(your_cmd)
# RESTORE PYTHONPATH
if ppsave != None: os.environ["PYTHONPATH"] = ppsave
else: del os.environ["PYTHONPATH"]
This way you can safely set PYTHONPATH just for your unix command
to run, then it changes it back so that maya has what it needs to
run normally.
Note: in my case, my OS's version of python works well with PYTHONPATH
completely unset. If that's what yours needs too, then change the above
line below 'CHANGE TO WHAT OS WANTS' to instead be:
# CHANGE TO WHAT OS WANTS
if os.environ.has_key("PYTHONPATH"): del os.environ["PYTHONPATH"]
This will make sure that variable is /unset/ before calling os.system()
so that the OS version of python won't see it set, and will use its own
defaults. (Probably better than trying to guess what those defaults are)
