That doesn't convey the idea of sorting, but  only of categorization,
i.e. (all assigned in whatever order) followed by (all unassigned
ones)

I'm also not sure explicitly telling where they appear is necessary:
that should be obvious from the UI.
Sthg like "Sort Assigned Mappings and Show them first" is probably
overkill IMHO.
