OrderedDict.viewitems() is expected to preserve item order like items() do
>>> from collections import OrderedDict
>>> d = OrderedDict([(1, 2), ("a", "b")])
>>> d.items()
[(1, 2), ('a', 'b')]

But it does not:
>>> list(d.viewitems())
[('a', 'b'), (1, 2)]

The effort to backport dictviews was incomplete.
Fixed in r84148.
Thanks for the report.
