ed9521ba4b reordered forked metrics to benefit from a stable sort 
nth_element does not honor the established order, so previously good
candidates can still be thrown out when the scores are the same.
Using a stable_sort keeps the order but is more costly.
We don't have a stable_partial_sort unfortunately and the one
provided as example, implemented using partial_sort and two aditional
comparisions to make it stable, is slower than a stable_sort.

f3d3afbe01 align parity bits accordingly 
if we want to use a crc aid at the end, we should move the start of the
first parity bit as far as possible to the front, otherwise we want the
last bit to be a parity bit
