Threaded commenting: how to show threads by last active first?

Hi all and happy holidays!

I have a page on which I enabled threaded commenting. At present, the comments are ordered new to old by when the thread started:

-Comment 3
-Comment 2
  -Comment 5
-Comment 1
  -Comment 4

Actually, I want the last active thread to be the first, in such a way that the listing would resemble:

-Comment 2
  -Comment 5
-Comment 1
  -Comment 4
-Comment 3

How could this be achieved?

Simply go to Settings > Discussion > Other comment settings > then look for the pull-down menu that will let you reverse the order.
