Here's what I do in my record collection stack.

-----
on mouseUp
  findBand
end mouseUp

on findBand
  set cursor to busy
  put (item 2 of the clickLoc) - (item 2 of the rect of field "Band Names") + the scroll of field "Band Names" into whichBand
  put (whichBand DIV textHeight of field "Band Names")+1 into whichBand
  select line whichBand of field "Band Names"
  put line whichBand of field "Band Names" into whichBand
  
  lock screen
  
  set cursor to busy
  go to first card of background "Record"
  find whole whichBand in field 1
  set cursor to busy
  if the result is not "not found"
  then
    unlock screen with iris open
  else
    go to card "root"
    unlock screen
    answer "Didn't find album by"&& whichBand & "." with "Fix list" or "Cancel"
    if it is "Fix list" then sortCards
  end if
end findBand

In your case, I would just delete the part of the script that does the
actual action, and keep the part that finds the line number and selects
the line.  You'll have to keep a global variable around for the last
line number selected, and the time at which it was selected in ticks.

You could also keep a hidden field with the ID numbers already
in it.  Calculate the line number, and find the appropriate ID number
to go to.
