Añadir javascript en mi tema de WordPress

Hola! estoy intentando añadir en mi tema 3 javascripts internos y uno externo pero no funciona,
los cargo en el archivo funtions.php de esta forma:

function load_scripts() {
  wp_register_script( 'scrollto', get_template_directory_uri() . '/js/jquery.scrollTo.js', array( 'scriptyouwillwaittobeloaded' ) );
  wp_enqueue_script( 'scrollto' );

    wp_register_script( 'scrolltomin', get_template_directory_uri() . '/jquery.scrollTo.min.js', array( 'scriptyouwillwaittobeloaded' ) );
  wp_enqueue_script( 'scrolltomin' );

  wp_register_script( 'serialscroll', get_template_directory_uri() . '/jquery.serialScroll', array( 'scriptyouwillwaittobeloaded' ) );
  wp_enqueue_script( 'serialscroll' );
}

add_action('wp_enqueue_scripts', 'load_scripts');

function load_myscripts()
{
wp_register_script( 'my_script', 'http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js');
wp_enqueue_script('my_script');
}
add_action('init', 'load_myscripts');

y en el head cargo el siguiente script

<script type="text/javascript">
