Often the simplest approach when sorting is to use a function called by
sort. For instance,

  on sortMeUp theBackground
    sort this stack by justBackground(theBackground)
  end sortMeUp

  function justBackground myBackground
    if the short name of this background is not myBackground then
      return "z"
    else return field "Name"
  end justBackground

The above will sort cards of the selected background by the background
field "Name", and sort cards of all other backgrounds to the end of the
stack (leaving their relative ordering unchanged). Of course, much more
complicated functions can be used.
