in reply to (OT) Boss asks "Incremental savings through Perl Scripts..." what to answer?

One other issue that can come up with this type of question is "What would it cost the company if we stopped maintaining these utilities?" Many tools are constantly evolving, meeting the needs of different sources, incremental features, and so on. If you stopped maintaining these tools, then each of these new features would need to be provided by the old manual methods. So a part of your value added would be the simple act of keeping these tools useful to your business.
