No, you use utime().

If you touch all the small files, then the big files will come earlier
in the list! If you want to get all the small files first, you can do
something like this:
#!/usr/bin/perl -w
if (opendir(CUR, ".")) {
map {
my @sb;
utime($sb[8], $sb[7], $_) if (@sb = stat($_));
} readdir(CUR);
closedir(CUR);
}
This sets the timestamp of all the files in the current directory to
their sizes. This is clearly a hack, but would probably work.

Your message prompted me to have a look at the code. Indeed it's roughly
sorted by the mtime of the messages. I say roughly because I did a pen-
and-paper test of the prioq functions and saw that it's not always fully
sorted.
