I don't buy this "choose the right tool for the job" thing. I'd always advise you to choose the tool that your company has the most knowledge in. If there's a problem that cannot be solved in that programming language, then you can look for a better tool. But you shouldn't pick a language that nobody else understands, just to save a few lines or some time when doing the initial implementation - just to realize that you now have to constantly keep up the knowledge to be able to support it.
