return map(lambda (key, x): x, nlist)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The argument list of the lambda method *must* not be put
into braces:

return map(lambda key, x: x, nlist)

AttributeError: 'tuple' object has no attribute 'startswith'

This is a Python Script bug. Works fine in Zope 2.6.4, breaks in 2.7.0 :

# copied from http://www.zope.org/Members/ontoprise/dls

------------------
parameter list = list, key

--------------------------
nlist = map(lambda x, key=key: (x[key], x), list)
nlist.sort()
return map(lambda (key, x): x, nlist)
--------------------------

inclusion of the third line "return map( ..." 
causes PyScript to give 

'tuple' object has no attribute 'startswith'

error message and refuse to save the script.
