Here is one approach, along with a function that sorts by spam score:

(add-to-list 'nnmail-extra-headers 'X-Spam-Status)
(defun gnus-article-spamassassin-score (header)
  "Return the Spamassassin score of this article, as a string."
  (gnus-replace-in-string
   (gnus-replace-in-string
    (gnus-extra-header 'X-Spam-Status header)
    ".*hits=" "")
   " .*" ""))
(defun gnus-user-format-function-s (header)
  (gnus-article-spamassassin-score header))
(defun gnus-article-sort-by-spam-status (h1 h2)
  "Sort articles by Spamassassin score."
  (< (string-to-number (gnus-article-spamassassin-score h1))
     (string-to-number (gnus-article-spamassassin-score h2))))

Now you can use "%us" in your gnus-summary-line-format to display the
spam score.  You could add to your spamtrap folder's group parameters:

 (gnus-summary-line-format "%U%R%z%I%(%[%6us: %-23,23f%]%) %s\n")
 (gnus-article-sort-functions
  '(gnus-article-sort-by-spam-status))

This displays the score for each article, and also puts the most
likely false positives at the top.
