Type safety would be the main plus point for me, even for tools and scripts. Plus I guess some people just prefer functional programming when they can and Haskell offers that in abundance. I guess the downside is the less portable nature of the code (this is where Clojure et al. would probably win...although writing command line tools and scripts in a JVM language still has a long way to go IMO)
