Problem:
The user would like to sort a view using a taxonomy.

Solution:
That's not possible without custom code to change the underlying SQL query. Because the WP_Query class does not offer this feature.

For a custom code solution, check this example http://scribu.net/wordpress/sortable-taxonomy-columns.html
