sorting data in simplelist

[Beast <beast i6x org>]

I have SimpleList which should be ordered by some column, what is the 
prefered way, sort the data before pushing into the stack or push data 
as is and then sort using SimpleList (possible??).
Some example would be greatly appreciated :)

FYI, data is coming from ldap, so I can not use 'order by' clause :)
