I might be off, but what exactly is this line good for?

As I understand the documentation, you are checking whether the
request URI of your packet is in the dispatcher set for group 7. But
unless you modify $ru somewhere above this snippet to match one of the
entries of your dispatcher set 7, this if statement should never
evaluate to "true", so the ds_select_dst("7", "8") is never evaluated.

Maybe your call gets dispatched by some other part of your main route?
