This handler is in my standard library stack used by most of my projects:

command enableScrollbarIfNeeded pFldName
  if the formattedHeight of fld pFldName > the height of fld pFldName then
    set the vScrollbar of fld pFldName to true
  else
    set the vScrollbar of fld pFldName to false
  end if
end enableScrollbarIfNeeded

It's worked well for me.
