How can I keep hyper links intact when I run the sortparagraph script?

Im working on a large catalog and have been hyperlinking products sections to the TOC. The client decided that the TOC needs to be in numerical order by product number. I tried to run the sortparagraph script but it does not retain the hyper link page locations. Instead its keeping the to the location.

For example if the list was like this before running the script:

321: (hyperlink to chair section)
231: (hyperlink to bathroom furniture section)
123: (hyperlink to desk section)
412: (hyperlink to table section)

after running “sortparagraph” script it does this:

123: (hyperlink to chair section)
231: (hyperlink to bathroom furniture section)
321: (hyperlink to desk section)
412: (hyperlink to table section)

Instead I want the hyper links to stay with the part number like this:
123: (hyperlink to desk section)
231: (hyperlink to bathroom furniture section)
321: (hyperlink to chair section)
412: (hyperlink to table section)

Any suggestions?
