You can't bypass Haskell no matter whatever FP language you want to learn. Because Haskell is like the textbook of all FP languages with a lot of important features.
And if you like scripting, try Clojure, it's immutable but much more dynamic and flexible. Since I'm a big fan of Clojure, I will suggest Clojure as the choice.
Other languages are also nice. Each of them emphasis' on a subset of the features, like immutable data, algebra data type, lazy evaluation, JVM integration, JavaScript integration, pure, S Expressions, performance... You'd better find out what you want most and choose the best one you can live with.
