Custom query with orderby meta_value of custom field

Aa you know, as of WP3.0 there are options for custom advanced queries, which is great.
As of this, some query parameters of custom fields like meta_key, meta_value were deprecated for the new meta_query parameter (see here)

I try to have a pretty simple query with the new syntax, query posts by a certain post_type (services) that contains a specified meta_key (order_in_archive)- this is going well as expected.
But – I want to orderby the query by the meta_value, and with no success.

This is my query –

   query_posts(
    array(  'post_type' => 'services',
        'order' => 'ASC',
        'orderby' => 'meta_value',
        'meta_query' => array(
            array('key' => 'order_in_archive'))
    )
);

I tried orderby also by meta_value_numeric and meta_value, but in any case the results are being ordered by the publication date (as regular posts do).
Anyone know how can this be done?

Thanks
