Both work.

Meh. Either one works, so it doesn't really matter.
The only slight difference is that if you have a single ordering item, a
single item list is less error prone that a single item tuple. People
keep forgetting that a single item tuple *must* have a trailing comma.
So you'll often see cases of using
['foo']
instead of
('foo',)
