Could we possibly have Clojure added to the languages? 

It runs on the JVM so you could download the clojure.jar and clojure-contrib.jar jars (Clojure 1.1 is the current version) and run programs with

java.exe -classpath "clojure-contrib.jar;clojure.jar" clojure.main %1

I will help test it if you like.

It would be a lot more fun for me and other Clojure programmers.  There were twice as many of us who qualified for GCJ this year as there were F# programmers.

I'm a native English speaker and I understood the problem statement fine.  It is almost all technically correct English but the choice of idiom is often foreign and not what a native speaker would naturally say.  Nevertheless I felt the statement was clear when read with sufficient patience.
