LP #1157382 - Provide a way to override default sorting in monograph parts

In the occasion that the current label_sortkey mechanism does not provide correct results,
allow explicit ordering in monograph_parts overriding derived label_sortkey.

The database schema change as part of this source change would need to be part of an upgrade
script.
