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).
