Order of nodes for <?cs each ?>

About ordering of nodes shown by 'each'.

I know this topic isn't new, it was first mentioned in msg #16 (with 
follow ups in #18 and #19). And I realize hdf_sort_obj() is in the 
sources.

My problem is *when* to run such function. I've tried it in a handler, 
but the handler doesn't seem to receive the nodes I'm interested in! 
(even though 'each' does list them, unsorted!)

...when exactly is that "prior to the template stage" phase?!

Thanks in advance,
Hugo.
