That would work. Use the rename command, and you've got it.
Another possibility is to have your build script split up the name and
apply a custom sort order to it.
The pattern is:
"rw" + version number + suffix
The suffices appear in this order: "dev", "alpha", "beta", "", "pat"
(where not all appear, e.g. "dev" never appears for a minor release,
and sometimes "alpha" is skipped).
