No. The numbers are entries in a table. If you remove an existing 
partition and create new partitions in that space, they will get higher 
numbers (higher indices in the table) while having lower physical 
addresses.

This is why things get out of order. Unfortunately parted does not have 
an option to reorder stuff. But gdisk can:

sudo gdisk /dev/sda
p (print/show)
s (sort)
p (print/show)
w (write)
q (quit)

If you wanted these numbers to always be in physical order, you would 
have to always do this reordering. It just doesn't happen by itself, I 
mean that the parted or gparted tool would also have to always reorder 
the tables.

They are just entries in a list. You have to reorder the entries if you 
want them to have increasing numbers on disk.

The reason, ostensibly, that parted (or gparted) does not do this on its 
own, or by itself, automatically, is because it might change your fstab 
entries and so on.

I know it seems peculiar and it is not very helpful to have out-of-order 
partitions but all the same it is just to prevent partition table 
operations to have disastrous consequences on the booting of the 
machine. Personally I wouldn't mind a parted option to sort. I would 
always sort myself. But if you used fixed identifiers such as /dev/sda3 
to reference anything in fstab or in Grub, you would have to change that 
after your work is done.

For me the best solution would be a "sort partition table" that every 
user can get used to.

That's all.
