There is no way round this that I know of with quicksort, or Shell sort
and Comb sort. None will maintain existing ordering and so are
unsuitable for multiple key sorts. In those cases using a fast sort
(one of the above) for the first key, followed by an insertion or
selection (but not the selection sort using exchanges posted by Tom and
Herman as a fast bubble sort) sort for subsequent key(s) is probably
best.
