Help with Cross-Tab Sorting by Summerized Field

I have a Cross Tab that looks similar to this:

NAME     2010     2011     2012     2013

CustA         31       87          5          45

CustB         52       58          7          99

CustC         24       78          9          77

Grand Totals

I am trying to figure out how to Sort the 2013 column summarized field in Descending order. 

I have scoured the internet, looked in books (both paper ones and PDF's) with zero success.

Desired result would look like this:

NAME     2010     2011     2012     2013

CustB         52       58          7          99

CustC         24       78          9          77

CustA          31          87     5          45

I suppress the Row Totals

My Year values are in my recordset that is passed to the report.

Any help would be greatly appreciated.
