emacs-lisp-mode and lisp-mode use different syntax tables.  I have

 (modify-syntax-entry ?\[ "(]" lisp-mode-syntax-table)
 (modify-syntax-entry ?\] ")[" lisp-mode-syntax-table)

in my .emacs to tell Emacs that square brackets are some kind of
parenthesis.

Depending on your Emacs version, you might also add

 (modify-syntax-entry ?# "' 14bp" lisp-mode-syntax-table)
 (modify-syntax-entry ?| "_ 23b" lisp-mode-syntax-table)
 (modify-syntax-entry ?\n ">a" lisp-mode-syntax-table)	

to get better handling of #| ... |# comments.

Helmut.
