Change line.

Line 15:

add_submenu_page('edit.php', 'Category Order', 'Category Order', 4, 'wpguy_category_order_options', 'wpguy_category_order_options');

to

add_submenu_page('edit.php', 'Category Order', 'Category Order', 'manage_categories', 'wpguy_category_order_options', 'wpguy_category_order_options');

Good plugin.
