Hey and thanks for your question! If you uses the AdvancedSearch interface you already can set the sort order as described. Just chose "Edit date - current on top" or "Creation date - current on top" in the "Sorting order" drop-down in the expanded interface.
Well, the current sort is based on last to first, compare descending edits (starting from 13 August 2019 -> 1 October 2012) - www.mediawiki.org/w/index.php?title=Special:Search/monkey&sort=last_edit_desc while www.mediawiki.org/w/index.php?title=Special:Search/monkey&sort=last_edit_asc shows results in the ascending direction (from 12 October 2012 to 13 August 2019 ).
The same applies to creation date. So if the current dropdown options are to be followed, it would need two extra items namely "Edit date - current at bottom" or "Creation date - current at bottom", or something like that.
I'll second this. If you add the ascending key manually you get a strange "advancedsearch-sort-unknown", see: https://www.mediawiki.org/w/index.php?search=foo&sort=create_timestamp_asc
