If there are multiple silent payment codes with the same scan key, sort the codes lexicographically in ascending order to determine the ordering of the ''k'' value. If there are multiple silent payment codes with the same scan key, sort the codes lexicographically in ascending order to determine the ordering of the ''k'' value.
If there are multiple silent payment codes with both the same scan and spend keys, sort the subgroup by output index in ascending order. If there are multiple silent payment codes with both the same scan and spend keys, sort the subgroup by output index in ascending order.
