get_taxonomies uses $wp_taxonomies internally.

Take another look at the code you posted previously. get_taxonomies is
returning an array of objects, not array of arrays. Secondly, if you
look at register_taxonomy the types you register a taxonomy to are
object types and not post types, i.e. $tax->object_type.

Whilst typing this Andrew replied again. You'll want to use his code,
but $tax->object_type and not $tax->post_type.
