You can assemble the lines to be selected into a comma-delimited list and
set the hilitedlines property of the field to that string:

 on mouseup
   get  the hilitedtext of me -- note this change from selectedtext
   put char 1 to 3 of word 5 of it into tcat
   put empty into tLineItems
   put 0 into tCounter
   repeat for each line i in me
      add 1 to tCounter
      if i contains tcat then put tCounter into \
        item (the number of items of tLineItems+1) of tLineItems
   end repeat
   set the hilitedLines of me to tLineItems
 end mouseup


This is off the top of my head, so it may need tweaking, but in the method
principle should work.
