"cateogry__and" work around

Hello!

So according to this: http://core.trac.wordpress.org/ticket/16157 and this: http://core.trac.wordpress.org/ticket/16706 …category__and has gone a bit AWOL. There’s a suggested workaround there in the form of this:

query_posts(array(
  'tax_query' => array(
    array( 'taxonomy' => 'category', 'terms' => 1 ),
    array( 'taxonomy' => 'category', 'terms' => 461 ),
  )
));

How can I work that above item, into my theme, which has this code for a query argument:

<?php $category_id = get_cat_ID($data['category']); ?>
                   		<?php $q = $category_id; ?> 

                   		<?php $catArgs = array(
                   			'category__and' => array($q, 6),
                   			'orderby'=>meta_value,
                   			'meta_value'=>student-sort,
                   			'order'=>ASC,
                   			'posts_per_page'=>5,
                   			'offset'=>0
                   		);?>

Any suggestions would be helpful.

Thank you!
