Own sorting relationship fields | WordPress.org

In the relationship field under the Relationship Options tab, see the Custom ORDER BY option, which takes a MySQL ORDER BY query.

By time, present to past:

CAST( t.post_date as DATETIME ) DESC

For a custom order, lowest to highest:

t.menu_order ASC

Menu Order can be enabled as a number when editing the pod under Advanced Options tab > Supports > Page Attributes, or using drag-and-drop on the post listing screen with Simple Custom Post Order.
