"""Compute the score of a key, relatively to its suffix.
When used by [`sorted`][sorted], the keys will only be sorted "at the suffix level".
The idea is that sometimes closely related keys in the state dict are not in the
same order as the one we expect, for instance `q -> k -> v` or `in -> out`. This
attempts to fix that issue, not cases where distant layers are called in a different
order.
Args:
key: The key to sort.
Returns:
The padded prefix of the key.
A score depending on the key's suffix.
