URL rewriting hack for custom post types

I am now using these rules:

add_action('init', 'create_rewrite_rules');
function create_rewrite_rules() {

  global $wp_rewrite;

  $custom_rules = array(
    'section' => '/%section%/%category%/',
    'news' => '/%section%/%category%/%year%/%monthnum%/%post_id%-%news%/',
    'jobs' => '/%section%/%category%/%post_id%-%jobs%/',
    'employers' => '/%section%/%category%/%post_id%-%employers%/'
  );

  foreach ( $custom_rules as $label => $url ) {
    $wp_rewrite->add_rewrite_tag("%" . $label . "%", '([^/]+)', $label . "=");
    $wp_rewrite->add_permastruct($label, $url, false);
  }

}

I get somewhat what I was looking for. Except, when I go to a jobs or employers page I get a page not found. It seems like the rewriting works only for news.

* myblog.com/jobs/aerospace/aviation/16-aviation-engineer/ does NOT work
* myblog.com/employers/aerospace/10-bombardier/ does NOT work
* myblog.com/news/aerospace/aviation/2011/05/13-good-aviation-news/ WORKS!

Thank you for your help.

I finally decided to go with this and it works…

add_action('init', 'create_rewrite_rules');
function create_rewrite_rules() {

  global $wp_rewrite;

  $custom_rules = array(
    'section' => '/%section%/%category%/',
    'news' => '/%section%/%year%/%monthnum%/%news%/',
    'jobs' => '/%section%/job-%post_id%/%jobs%/',
    'employers' => '/%section%/employer-%post_id%/%employers%/'
  );

  foreach ( $custom_rules as $label => $url ) {
    $wp_rewrite->add_rewrite_tag("%" . $label . "%", '([^/]+)', $label . "=");
    $wp_rewrite->add_permastruct($label, $url, false);
  }

}

Keep me posted though if you find something useful for me.
