I have a report showing the version history of a list item. All is well with the exception of the _UIVersionString column sort order. It seems that no matter what I do it always displays newest to oldest:

3.0
2.0
1.0

I need to show oldest to newest

1.0
2.0
3.0

Below is the CAML used.... I added <FieldRefName ="_UIVersionString"/> with no luck; ascending or descending, the order never changes.

<?xml version="1.0" encoding="utf-8"?>
<root xmlns="http://enesyssoftware.com/schemas">
  <queryName></queryName>
  <description></description>
  <list title="Review Comments" relativeSiteUrl="/ipoms/pakistan/" tableName="Review Comments" stripHtml="true" itemVersions="0">
<fields>_UIVersionString,Modified,Editor,Track,Lesson,Document_x0020_Type,Comment_x0020_Category,Page_x0020_or_x0020_Slide_x0020_,Origin,Comment,Customer_x0020_Priority,Contractor_x0020_Comment,ID,Status</fields>
    <query>
      <OrderBy>
        <FieldRef Name="Track" />
        <FieldRef Name="Lesson" />
      </OrderBy>
    </query>
  </list>
  <resultSet>Review Comments</resultSet>
</root>

Can you help?

Thanks, Bill
