Great post Michael, i did a python module to do that, and i called the
function isorted (but its principle can be used in a django filter too).
Here is the code:

Please, if you have any comments on how to improve it, or if i have to
do something to add it to django (im a newbie in django core
development) just say it and im sure to do my best.
Also sent this to Marinho to see if we could put in django-plus.
Thanks a lot and i really hope that we can find a way to improve this in
django.
