The answer to both of your questions is No.
What I have is a stacked list and apparently this issue will never be resolved.
I even had a supervisor said he would ask that we be given an option to display the list contents the way we wanted, but that was over a year ago and nothing was ever done.
Which tells me either Apple script writers don't have the knowledge to reverse the list order or they don't care.
As I've already mentioned, the list displayed alphabetically from top to bottom when I was running Snow Leopard!
