shell-script-mode is an alias for sh-mode, the hook is called
sh-mode-hook.  Anyway, I think it's easier to define the
:enable-function property on your abbrev table.

(abbrev-table-put your-abbrev-table
                  :enable-function
                  (lambda nil
                    (not (nth 4 (syntax-ppss)))))
