   Something like this:
from DTML import SortEx # I m not sure about "DTML", may be "from DT_Util" or such
for item in SortEx(folder.objectValues('lala'), (("something",),))
   The second rgument is a tuple of tuples that lists sort prameters. Every
inner tuple constructed as follows:
   (attribute, function, order)
where "attribute" is an attribute of the object you want to sort on,
"function" is a comparison function, and "order" is "ASC" or "DESC". You my
use predefined comparison functions "cmp", "locle" (alias "strcoll"),
"nocase" and "locale_nocase" (alias "locale_strcoll"). You may omit sort
order (default is "ASC"), or you may omit both function (default is "cmp")
and sort order. You cannot omit function, but use sort order; use "cmp" as
a function.
