I have a selection set

Now I need re arrange this list as  mirror order of selection.

You process the selection set last to first

 

last to first
(repeat (setq x (sslength lst))
(setq ent (ssname lst (setq x (- x 1))))
do your thing ....
)

first to last
(setq x 0)
(repeat (sslength lst)
(setq ent (ssname lst x))
do your thing .....
(setq x (+ x 1))
)
