I am fine with the current lambda syntax, but another possibility:
sorted(range(9), n => n % 3)

Given the recent pattern of syntactic constructs for expressions using
(ternary if, listcomps, genexps), and avoiding
the use of colon in expressions, maybe it should be:
sorted(range(9), k

This proposal (a) ignores Guido's clear-cut decision that lambda is
good as it is, (b) is weird in proposing a special-case syntax, (c) is
several Python versions too late for a graceful transition by 3.0.
But I don't won't to just throw the idea away, so I'm posting here.
