Hi,
You could take a look at:
Perl\html\lib\sort.html
To summarize V5.8 seems to be using the merge sort algorithm which is
stable, i.e. maintains the original ordoring in elements that are determined
to be equal. 5.6 and earlier use a quick sort by default and it is not
stable. In 5.8 at least, you can choose which algorithm should be used with
the sort pragma that the above HTMl page in Active State Perl documents.
Hope this can be of help.
