With a trailing full length, the last comes first and the first last, with those in the middle keeping their correct relative ordering

So, don't use the actual length, use length mod 4.

input	packed
ACGT	1b 00
ACGTA	1b 01
ACGTAA	1b 02
ACGTAAA	1b 03
ACGTAAAA	1b 00 00
ACGTAAAAA	1b 00 01

Your example in string (byte) sorted order:

input       packed    
ACGT        1b 00    
ACGTAAAA    1b 00 00    
ACGTAAAAA   1b 00 01
ACGTA       1b 01    
ACGTAA      1b 02    
ACGTAAA     1b 03
