The algorithm that is used is sophisticated enough to take cards with
configured CA as the latest card. Don't worry it works as you expect. 

Here is the relevant code part:
+         if (device[i]->Receiving() && !ndr)
+            pri = 0; // receiving and allows additional receivers
+         else if (d && !device[i]->Receiving() &&
device[i]->ProvidesCa(Channel->Ca()) < d->ProvidesCa(Channel->Ca()))
+            pri = 1; // free and fewer Ca's
+         else if (!device[i]->Receiving() &&
!device[i]->IsPrimaryDevice())
+            pri = 2; // free and not the primary device
+         else if (!device[i]->Receiving())
+            pri = 3; // free
+         else if (d && device[i]->Priority() < d->Priority())
+            pri = 4; // receiving but priority is lower
+         else if (d && device[i]->Priority() == d->Priority() &&
device[i]->ProvidesCa(Channel->Ca()) < d->ProvidesCa(Channel->Ca()))
+            pri = 5; // receiving with same priority but fewer Ca's
+         else
+            pri = 6; // all others
+         if (pri < select) {
+            select = pri;
+            d = device[i];
+            if (NeedsDetachReceivers)
+               *NeedsDetachReceivers = ndr;
+            }
