I wrote a plugin that extends SyntaxHighlight Evolved and adds support for AppleScript:
SyntaxHighlighter Evolved Applescript
One fix that ‘seems’ to work is to add a line after 198 in http://plugins.trac.wordpress.org/browser/comments-notifier/trunk/comments-notifier.php#L198
Find (around 195-198):
function wp_notify_allmods($comment_id) {
global $wpdb;
$comment = $wpdb->get_row("SELECT * FROM $wpdb->comments WHERE comment_ID='$comment_id' LIMIT 1");
Add this after it reads the comment information
if($comment->comment_approved == "spam") {return;}
