Jordan Times and other sources say that Jordan is going back to UTC+2 on 2013-12-19 at midnight: http://jordantimes.com/govt-decides-to-switch-back-to-wintertime (in English) Official, in Arabic: http://www.petra.gov.jo/public_news/Nws_NewsDetails.aspx?Menu_ID=&Site_Id=2&... We assume they mean going back from 2013-12-20 00:00 to 2013-12-19 23:00, but it could also be one hour later, which is what they have normally done in the past. Based on the wording in the article, they call it coming back to winter time, so I think it would be best to change the Rules for Jordan and Zone for Amman, so it says DST started back in March 2012, never ended for the 2012/2013 winter and lasted all to December 2013.
