It's not easy to delete a WordPress.com blog URL. To prevent accidental or inadvertent deletion of blogs, there are multiple warnings given that blog deletion is permanent and irreversiable. Lastly, a verification link is sent in an email and must be clicked to delete a blog. If clicking that link does not work then copy and paste it into your upper browser window and click.
To be clear on this you cannot register a deleted URL. Deleted blog URLs are not recycled, regardless of who registered and deleted them and no exceptions are made.
You can register another blog with a similar name. http://en.support.wordpress.com/register-a-blog/
Or you can register a domain via a domain mapping upgrade and it will not matter what the underlying .wordpress.com address is.
Note: Your followers subscribe to follow a specific blog URL. that URL is now history. When you register a new blog they will be able to subscribe to it.
