[Plugin: Yet Another Related Posts Plugin] Numbered list before each post like default template

I like the look of the default template when the “Automatically display related posts?” box is checked. Although I needed to add the related_posts(); tag to my single.php file to better position where the Related Posts list appears on my pages.

The default template would display the posts like this:

1. Post 1
2. Post 2
3. Post 3

and so on. Notice the 1, 2, 3 before each post.

By turning off the “Automatically display related posts?” (to use the related_posts(); tag) the Related posts are now displayed like this:

Post 1
Post 2
Post 3

How do I get the numbered list to show up in front of each post line like before?
