Steps to reproduce:
1. Create more than one workflow tagged as 'editor' and set their display order.
2. Go to the edit screen.
Workflows are not sorted by display order.
Workflows should be sorted by display order (highest first).
Workaround (if any):
Come up with workflow titles to make them appear in the desired order.
Reason: 1) the tools endpoint does not currently return the display order field, 2) the second workflow drop-down doesn't sort by display order (editor screen).
