I'd try two things:

- Just guessing here, but perhaps the problem with your test is that
your working copy is "mixed-revision" after you added the three files.
I.e. the 'trunk' directory is a revision behind, after you added the
three files. See if it makes a difference if you do "svn up $wc_root"
before performing the "svn copy trunk branches/stable".

- Maybe you can get what you want by performing a server-side copy,
instead of in your working copy and then committing. I.e. "svn copy
$url/trunk $url/branches/stable".
