I would use an XFBR that reverses the order.  

Something like 
Given that input is  "Feb 24, Mar 24, Apr 24, May 24, Jun 24, Jul 24, Aug 24, Sep24, Oct 25, Nov 25, Dec 25"

code the reverse as:
Dim reversed As String = String.Join(", ", input.Split(","c).Select(Function(s) s.Trim()).Reverse())
Return reversed

Edit: I just realized this is an ideastream.  oh well, there's a suggestion.
