Do they show up numerically in the sequence in which they appear in
the device tree?
Where could I learn more?

Adding devicetree ML to Cc.
You may use an "aliases" node for that, if your UART driver supports that. The
8250/16550 driver does. See arch/arm/boot/dts/aspeed-ast2500-evb.dts, for
example. Note though that the use of aliases for this purpose is contentious.
