Tag base listing through shortcodes

Hi,

We are trying to create some detail pages based on tags. We have found the shortcode for the listing but how can we call any tag based listing.

ex. Current listing shortcode is : [gd_listings post_type=”gd_place” layout=4 category=”1,3″ post_number=”4″ list_sort=”high_review”]

now in place of Category we want to listing should be based on Tag based. Ex. [gd_listings post_type=”gd_place” layout=4 Tag=”Math Tuition” post_number=”4″ list_sort=”high_review”]

So in this case listing would be ceated for the Math Tuition (and math tuition is Tag)

Pls. suggest.
