If they're the ones I think you mean, those icons are done through markup. They don't really have anything to do with the status bar (other than that they can be used on it as well as other places).
Having to guess a bit here, without concrete examples of what you want to do.
Support for markup in script columns was added in Directory Opus 13.11.1 (Beta) - see the Scripting part of that for the details, and make sure you have the latest beta installed (at least until 13.12 is out, which will add the new functionality to a stable release).
