I would like to note, that ST_Area also works, although Django denies its execution:

Region.objects.order_by(RawSQL('ST_Area(polygon)', params=[]))
<QuerySet [<Region: Region object (1)>, '...(remaining elements truncated)...']>

in contrast that errors with contributed Area:

from django.contrib.gis.db.models.functions import Area
Region.objects.order_by(Area('polygon'))
...
django.db.utils.NotSupportedError: Area on geodetic coordinate systems not supported.

Please uncheck "patch needs improvement" after addressing the test failures and other review comments. If the tests are passing locally, perhaps it's a difference between the versions that Jenkins uses.
