Why is only 1256 used, and not 3 and 4?

Because it takes up less space.

1-6 takes up even less space, with the added benefit of being easy to
understand. So why use a form where some might think that zones 3 and 4 are
not included? Is space the only reason R1256 is used?

You'd be amazed how many people forging tickets don't check things like
this (or using JAN instead of JNR). It's harder to alter R1234 into
R1256 than to alter R1-4 into R1-6.
