After talking to obenland, we came up with a more straightforward solution. I tested it on different screens and also with a couple of plugins that add meta boxes to the menu screen. Works like a charm.

diff --git src/wp-admin/includes/screen.php src/wp-admin/includes/screen.php
index 582c659..4e40efc 100644

  function meta_box_prefs( $screen ) {
         $hidden = get_hidden_meta_boxes($screen);
         foreach ( array_keys($wp_meta_boxes[$screen->id]) as $context ) {
+                foreach ( array_keys($wp_meta_boxes[$screen->id][$context]) as $priority ) {
+                foreach ( array('high', 'core', 'default', 'low') as $priority ) {
+                        if ( ! isset( $wp_meta_boxes[$screen->id][$context][$priority] ) ) {
+                                continue;
+                        }
                         foreach ( $wp_meta_boxes[$screen->id][$context][$priority] as $box ) {
                                 if ( false == $box || ! $box['title'] )
                                         continue;
