Change the bare assert to generate more info, e.g.:

   if script.meta_type != meta_type:
       raise ValueError('Invalide meta_type (%s) for object %s'
          % (script.meta_type, script.getId()))

and debug from there.  You might also add the PDBDebugMode product to
your instance, which would allow you to put an
'import pdb; pdb.set_trace()' inside the script.
