Classifieds Default listing list order does not work as expected

If I set Default listing list order to Last updated, I expected to see those listings at the top that were recently added or modified.
But in fact it will only display those listings on top that were recently modified (as last_edit_date is 0 for listings that have never been edited).

IMHO, this does not make much sense as many listings most likely will never be edited and thus will be shown in no deterministic oder below listings that have been edited at some point in time.
