Price set option order not being respected

When you create a price set item that is a select with a list of options, the "order" parameter is not being respected in some displays. This is reproducible, and here is an example on the civihosting demo site:

https://demo.civihosting.com/civicrm/admin/price/field/option?action=browse&reset=1&sid=9&fid=10

On this screen, the items are listed in the order of their oids, rather than the order of their Order setting. (I've put both values into the label names.)

Furthermore, on the edit screen, clicking the "move to bottom" arrow on one of option items does not affect the displayed order.

Interestingly, the Preview drop-down does seem to respect the Order:
