How can I list partitions in storage order?
I don't know of any program that does this, but it's easy enough to sort if all you want is the list of partitions. For example, on my system:

How can I list partitions in storage order?
One tool that lists partitions in the order they are on disk is partedso e.g. using sector as unit size, if you run (as root)
parted /dev/sda unit s print
you get

I assume you mean "a PTUUID for the disk and PARTUUIDs for the partitions", since there is no such thing as "PTUUIDs for partitions".

Are UUIDs and PTUUIDs important for MBR disks? If so, how do I create them on my own?
This leads me to think that UUIDs and PTUUIDs are not necessary for MBR drives.
That's mostly correct. PTUUIDs on the partition table itself don't serve any purpose to MBR itself, but it's used by ...
