Query posts by custom taxonomy term name

Hi,

I would love to get the list of posts by their custom taxonomy (=store) name.

Here is what I have so far, but it is not working.

Please help with the code.

$postslist = query_posts('numberposts=5&order=DESC&orderby=meta_value&showposts=5&meta_key=hits&post_type=post&store='.$mystorename); if(count($postslist) > 0){ ?>

‘Store’ is the custom taxonomy
$mystorename is a variable holding the name of the store i want to query by.

Any help will be appreciated.

Thank you
