If functional languages are really concise, why don't they have a better rank in the language shootout game?

I compared the languages at the language shootout game by their code size only. Here is a summary of what I got (shortest first, grouped by similar score).

1. Python, Ruby, JavaScript, Perl, Lua, PHP, Mozart/OZ
2. OCaml, Erlang, Racket, Go, Scala, F#, Smalltalk
3. Pascal, Clean, Haskell, Common Lisp, C#, Java, C
4. C++, Ada, ATS

I wonder why. The winners seem to be plain old dynamic languages. Erlang, Racket (née PLT Scheme), and F# are doing OK. Haskell and Common Lisp don't look more concise than claimed-to-be-verbose Java.

UPDATE:

I've found an insightful post on this topic with charts. I also found a similar comparison of languages for a larger program (a simple ray tracer). Altogether, I wouldn't say I got "the" answer, but I got some food for thought.
