Bug on comment-reply inclusion breaks singular post pages

On line 75 of function.php

//Enqueue comment thread js
function roadfighter_enqueue_scripts() {
    if (is_singular() and get_site_option('thread_comments')) {
        wp_enqueue_scripts('comment-reply');
    }
}

add_action('wp_enqueue_scripts', 'roadfighter_enqueue_scripts');

The correct function name is ‘wp_enqueue_script()’, without the final ‘s’.

In the current implementation, wp_enqueue_scripts() calls the hook itself, leading to a loop which ends with a 500 error.
