Much as I agree with your sentiments, in many environments, the use of ISO 9000 is *required*, as in you don't get the contract if you don't follow ISO 9000. I have not seen any evidence, personally, that ISO 9000 actually ensures a perfect product, but it is a political requirement of many environments.
Sure, there's no question that much of ISO 9000 is useless, but I also don't see the relevance here. As I understand it, ISO 9000 talks about documentation of process, not process itself. No matter how kludgy a script might be, if it's properly documented in the procedures, there's no problem using it, at least as I understand it.
