Comment (by jesin):

 How about padding the slug with a leading zero?

 I found another bug, not sure if there is a ticket for it.

 1. Set the permalink structure to `%postname%`.
 2. Create a **post** with slug `foo-bar`.
 3. Create a **page** with the same slug `foo-bar`.

 Now the URL **example.com/foo-bar/** loads the **page** created in step 2.

 Problem lies in `wp_unique_post_slug()` which checks for uniqueness only
 within the post type.
