A dictonary can't be sorted. If it once is, it happens by chance.

What you have to do is to put the items of a dictionary into a list
which you can sort.
>>> myDict={(1, (21353, 21418)): 3900, (2, (53006, 53164)): 3800, (0,
(19697,19763)): 4100}
>>> myDict
{(2, (53006, 53164)): 3800, (0, (19697, 19763)): 4100, (1, (21353,
21418)): 3900}
>>> myItems=myDict.items()
>>> myItems.sort()
>>> myItems
[((0, (19697, 19763)), 4100), ((1, (21353, 21418)), 3900), ((2,
(53006, 53164)), 3800)]
