Genesis loads the child theme stylesheet very early in the process. This will make sure you child theme's stylesheet loads after the parent theme.

Genesis framework: Load Parent stylesheet after child

//Don't have Genesis load child theme styles
remove_action( 'genesis_meta', 'genesis_load_stylesheet' );

//* Load parent stylesheet first, then load the child stylesheet
add_action( 'wp_enqueue_scripts', 'load_theme_scripts' );
function load_theme_scripts() {	
  wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css', array(), CHILD_THEME_VERSION );
  wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() . '/style.css', array( 'parent-style' ), CHILD_THEME_VERSION );
}
