Try using the hook-stop instead.  Something like this:

 set $stop_recording_on_next_stop=3D0

 b functon_name
  commands
  silent
  record
  set $stop_recording_on_next_stop=3D1
  finish
  end

 define hook-stop
   if $stop_recording_on_next_stop=20
     set $stop_recording_on_next_stop=3D0
     record save
     record stop
     end
   end

--=20
