sorted(d) is guaranteed to do exactly the same thing as sorted(d.keys())
AND to be faster (would be pretty weird if it weren't faster...!).

E.g., ...:

helen:~ alex$ python -mtimeit -s'd=dict(enumerate("tarazoplay"))'
'sorted(d.keys())'
100000 loops, best of 3: 6.82 usec per loop

helen:~ alex$ python -mtimeit -s'd=dict(enumerate("tarazoplay"))'
'sorted(d)'
100000 loops, best of 3: 5.98 usec per loop
