Like any namespace, attributes of an object are implemented as a
dictionary. Dictionaries have no guaranteed order to their items.

If you want to preserve order, do so with a type that preserves such
order:

class Test(object):
    ordered_things = [
        ('y', 11),
        ('x', 22),
        ]

If that doesn't meet your needs, perhaps you could describe what
problem you're trying to solve and we can address it better.
