Thanks for catching this missing 'draft' modulestore - it was an oversight on my part.

Small nit pick here. My IDE is showing a PEP8 violation: need a whitespace after the comma.

export_to_xml(ms, cs, location, root_dir, course_dir, modulestore())
except Exception as err:
print "="*30 + "> Oops, failed to export %s" % course_id
print "Error:"
print err

Two PEP8 violations here. Extra line at end of file (remove this last one). Also 'blank line contains whitespace'.

We're closely tracking PEP8/Pylint violations on our builds, so we like to try to avoid introducing new ones.
