What does this number indicate?

What does the number, "12" indicate in the following snippet:
remove_action( 'genesis_entry_header', 'genesis_post_info', 12 );

I see this throughout my PHP and the number changes. I try to see the connection/pattern as to why this is put in my code, but I fail to see it and I figured this is as good a place to ask as any.

Priority.

This is useful with adding multiple functions to the same hook. Example:

add_action( 'genesis_entry_content', 'genesis_do_post_image', 8 );
add_action( 'genesis_entry_content', 'genesis_do_post_content' );
add_action( 'genesis_entry_content', 'genesis_do_post_content_nav', 12 );
add_action( 'genesis_entry_content', 'genesis_do_post_permalink', 14 );

The lower then number the sooner the code will execute. If you wanted to add the post title just under the post image you can do something like

add_action( 'genesis_entry_content', 'genesis_do_post_title', 9 );

or above it with

add_action( 'genesis_entry_content', 'genesis_do_post_title', 7 );
