query_posts doesn't order by title

Question

It seems like stupid bug, but how can i order by title? It anyways orders by date! I'm using:

query_posts( array( 
    'post_type'      => 'page',
    'posts_per_page' => -1,
    'orderby'        => 'title',
    'order'          => 'ASC'
) );

I want to use this in function as SHORTCODE. What i'm trying to achieve is to create site map / index of all entries in alphabetic order. Also i'm using newest WP.
