Rearrange Pages in Reverse Order

Here's a simple script to reverse all pages:

for (var i = 0; i < this.numPages; i++) 
{
this.movePage(i, -1);
}

If you want a specified range of pages that isn't all the pages, you would need to change 3 numbers in the script above.  For example, if you wanted to leave the first 2 and the last 2 and reverse the pages in between the script would be modified like this:

for (var i = 2; i < this.numPages-2; i++) 
{
this.movePage(i, 1);
}

Remember that page numbers are zero-based.  Use it an Action to Execute Javascript.  You could also add a popup dialog at the beginning of the Action to specifiy the page range.
