Maybe they just transposed a few digits? It happens. Somebody should try swapping them in and see if the pattern fits better.
The Sumerians used a sexagesimal notation system; the two lengths would be 5.10.0 and 5.50.0 (which together add up to 11.0.0, FWIW), while all of the other king lengths are 8.0.0, 10.0.0, or 12.0.0.
I ran it through the provided program and the alignment was worse if anything.
