What you see is caused by the following code in
"DocumentTemplate.DT_In.InClass.__init__":
if has_key('sort'):
self.sort=sort=args['sort']
if sort=='sequence-item': self.sort=''
This means, "dtml-in sort=sequence-item" does not sort
by "sequence-item" but by the complete tuple (key,item).
I think, the special treatment of lists of pairs is
altogether a slight misfeature. It would probably
have been better to use a special "dict" attribute
in analogy to the "mapping" attribute to call
for the special pair interpretation.
'sequence-item' should then still be the complete item
and 'sequence-value' the second pair component.
Probably, it is too late by now to change this.
