Error in a date display order in search results on EPDM

A customer of ours is an interesting problem. When it opens thorough research and do a search, the sort the display by date modified, EPDM sorts in order Cardinal, not by the sequence of dates. It groups, for example, all that is 1 day, independent of the month after 2 days and so on.

01/01/2014

02/01/2014

01/03/2014

02/01/2014

02/04/2014

09.02.2014 and so forth.

I imagined at first that in the "Variable Type" in the variable "Date Modified" could be labeled the "Text", but when checking, I found that this marked the "Date" option. But even so the system does not present the research in date order correctly.

Someone has seen this problem?
