The guarantee is that the items' order as the value for each key will exactly match the order they were submitted by the form. I'm pretty sure that means the answer to your question is "yes", but I can't immediately find the right paragraph in the HTML spec that says that. The relevant code (where we construct the QueryDict) is in django/http/__init__.py. It relies on the fact that Python's cgi.parse_qsl() function is order preserving.
