The only way to make it work with sorta is if the two fields are
adjacent in the array element _and_ in the right order _and_ are both

They also have to be fixed-length character fields.
But I think qsort is better for this purpose anyway even if they were
both fixed length character. Once you have qsort set up, it's easy to
modify it to change how the comparison is done. (It's not hard to set up
in the first place.)
Using the technique where you use a character overlay to sort several
subfields is kludgy and if if it's not very carefully and visibly
documented, it's error prone.
