Hook ‘wp_enqueue_scripts’ priority has no effect

In a theme I am working there are up to 3 Stylesheets. I am using the hook ‘wp_enqueue_scripts’. The order of the stylesheets is important for overwriting styles.
I have a code like this:

add_action('wp_enqueue_scripts', 'add_stylesheet_one', 10);
add_action('wp_enqueue_scripts', 'add_stylesheet_two', 14);
add_action('wp_enqueue_scripts', 'add_stylesheet_three', 12);

With this priorities the stylesheet order should be ‘stylesheet_one’, ‘stylesheet_three’ and ‘stylesheet_two’. But the priority doesn’t have any effect. I’ve tried different numbers but the order does not change.
Am I missing something?

Thx for Help!!!

The problem is that your actions are being run in the order you perceive but the styles are just being collected by WordPress and included in a random order.

The order of your add_actions will not be important. I would do this:

function add_all_stylesheets() {
  // you omitted this from your question, see below
}
add_action('wp_enqueue_scripts', 'add_all_stylesheets');

Now – if you’d like your scripts to be included in order you’ll need to have them “depend” on each other so they cascade.

function add_all_stylesheets() {
  wp_enqueue_style( 'stylesheet-one', get_template_directory_uri() . '/css/stylesheet-one.css' );
  wp_enqueue_style( 'stylesheet-two', get_template_directory_uri() . '/css/stylesheet-two.css', array( 'stylesheet-one' ) );
  wp_enqueue_style( 'stylesheet-three', get_template_directory_uri() . '/css/stylesheet-three.css', array( 'stylesheet-two' ) );
}
add_action('wp_enqueue_scripts', 'add_all_stylesheets');

Now your “stylesheet-two” depends on “stylesheet-one” and “three” depends on “two. This should be the effect you want.
