Will this generate bugs?

Hello, I add some lines at the function wp_insert_comment() (/wp-includes/comment-functions.php)

the original code was
function wp_insert_comment($commentdata) {
global $wpdb;
extract($commentdata);
if ( ! isset($comment_author_IP) )
$comment_author_IP = $_SERVER['REMOTE_ADDR'];
if ( ! isset($comment_date) )
$comment_date = current_time('mysql');
if ( ! isset($comment_date_gmt) )
$comment_date_gmt = gmdate('Y-m-d H:i:s', strtotime($comment_date) );
if ( ! isset($comment_parent) )
$comment_parent = 0;
if ( ! isset($comment_approved) )
$comment_approved = 1;
$result = $wpdb->query("INSERT INTO $wpdb->comments
(comment_post_ID, comment_author, comment_author_email, comment_author_url, comment_author_IP, comment_date, comment_date_gmt, comment_content, comment_approved, comment_agent, comment_type, comment_parent, user_id)
VALUES
('$comment_post_ID', '$comment_author', '$comment_author_email', '$comment_author_url', '$comment_author_IP', '$comment_date', '$comment_date_gmt', '$comment_content', '$comment_approved', '$comment_agent', '$comment_type', '$comment_parent', '$user_id')
");
$id = $wpdb->insert_id;
if ( $comment_approved == 1) {
$count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_post_ID = '$comment_post_ID' AND comment_approved = '1'");
$wpdb->query( "UPDATE $wpdb->posts SET comment_count = $count WHERE ID = '$comment_post_ID'" );
}
return $id;
}

and here is the edited one

function wp_insert_comment($commentdata) {
global $wpdb;
extract($commentdata);
if ( ! isset($comment_author_IP) )
$comment_author_IP = $_SERVER['REMOTE_ADDR'];
if ( ! isset($comment_date) )
$comment_date = current_time('mysql');
if ( ! isset($comment_date_gmt) )
$comment_date_gmt = gmdate('Y-m-d H:i:s', strtotime($comment_date) );
if ( ! isset($comment_parent) )
$comment_parent = 0;
if ( ! isset($comment_approved) )
$comment_approved = 1;
if ($comment_post_ID == '32' or $comment_post_ID == '84')
$comment_approved = 0;
$result = $wpdb->query("INSERT INTO $wpdb->comments
(comment_post_ID, comment_author, comment_author_email, comment_author_url, comment_author_IP, comment_date, comment_date_gmt, comment_content, comment_approved, comment_agent, comment_type, comment_parent, user_id)
VALUES
('$comment_post_ID', '$comment_author', '$comment_author_email', '$comment_author_url', '$comment_author_IP', '$comment_date', '$comment_date_gmt', '$comment_content', '$comment_approved', '$comment_agent', '$comment_type', '$comment_parent', '$user_id')
");
$id = $wpdb->insert_id;
if ( $comment_approved == 1) {
$count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_post_ID = '$comment_post_ID' AND comment_approved = '1'");
$wpdb->query( "UPDATE $wpdb->posts SET comment_count = $count WHERE ID = '$comment_post_ID'" );
}
return $id;
}

(lines 15 and 16 were the ones that I added)

Now, I just want to ask if this will generate bugs. You see, I want all comments that would be posted with the post number 32 or 84 undergo comment moderation. Thanks!
