Issue:Use of multiple dates

Description:	Use of multiple dates in ordermethod

Problem

I have a dpl query as follows.

<dpl> debug=1 category=Scrum ordermethod=firstedit,lastedit addeditdate=true userdateformat=Y-m-d listseparators={{{!}} class="wikitable sortable" cellpadding="2" border="1" width="100%" \n {{!}}- bgcolor="#ffcc33" \n {{!}} Iteration\n {{!}} Updated\n ,\n{{!}}-\n{{!}}[[%PAGE%{{!}}{{SUBPAGENAME:%PAGE%}}]],\n{{!}}%DATE%\n,\n{{!}}} nottitlematch=%Template% include= titlematch={{BASEPAGENAME}}/% includetrim=true stablepages=only </dpl>

the expected behavior because i have the addeditdate parameter would be that %DATE% is the edit date, this is true. however the sorting is only sorting on the last value from ordermethod and not obeying the firstedit.
