I was just starting to write "It doesn't work" when I found this here:
http://www.djangosnippets.org/snippets/1767/

class LazyChoiceField(forms.ChoiceField):
def __init__(self, *args, **kwargs):
# remove choices from kwargs
self._lazy_choices = kwargs.pop('choices',())
super(LazyChoiceField,self).__init__(*args, **kwargs)

def __deepcopy__(self, memo):
result = super(LazyChoiceField,self).__deepcopy__(memo)
result.choices = self._lazy_choices
result.choices.sort(lambda x, y: cmp(x[1], y[1]))
return result

Just needed to add the line with the sorting to the snippet. Well,
actually I don't really understand why it works and when django calls
the __deepcopy__, but supposedly it is called after the translation
takes place, so this is an effective solution. Could be generalized
further (not hardcode the sorting function), but for now it does the
job.
