Jason Franklin 4a487474c4 Modify call to sort() for older versions of Vim (#714)
Older Vim versions seem to require that calls to sort() specify a
dictionary when the compare function argument is a dictionary
function. This seems to be required even when the dictionary is not
used. Since this change does not seem to affect behavior in later
Vim editions, I see no harm in including it.
