This is a common pattern, but not required.  If sorting is
interesting, there are a couple of reasonable approaches:

1.  Make the vocabulary responsible for the ordering.  This is
reasonable when there's one sensible way to sort the values.

2.  Make the widget sort the data.  This means writing new widgets,
and getting them hooked up properly.  The vocabulary pretty much
requires a specific interface at this point to act as a marker for
widget selection.  This is better if there are multiple reasonable
ways to sort the values, especially if the user might want to switch
between sort orders in the UI.

Clearly, the first option is easier.  I don't know if anyone has
bothered to use the second option.

The same pattern options apply to sources as well as to vocabularies.
