On digging a little more, it looks like you only get automatic include behavior
if you're sorting on a belongs_to (a feature I forgot existed):
parse_sort_param('user',...)
The code that I'm using those scopes in does an explicit :include => [:user,
...] to make sure the required tables are involved. This is useful as well, as
the code won't need to execute additional DB queries to display data from the
associated records.
Sorry for the confusion!
