I think the "Unix way" would be to pipe the output of "svn list URL" to
a separate sorting program.

The man page for "sort" didn't hint at a way to get it to do
natural-order sorting, so here's a PHP script you can pipe your output
through:

#!/usr/local/bin/php
<?php

$lines = array();
while (($line = fgets(STDIN, 1024)) !== false) {
        $lines[] = $line;
}

usort($lines, 'strnatcmp');

echo implode($lines, '');

?>

This doesn't have "sort"'s nice ability to specify which
space-delimited field to sort on, but that could of course be added.

You could undoubtedly write a similar script in Perl or Ruby or C or
any other language you like; I just happen to like PHP.

Ways to do this in Perl, Ruby and C are available here:
