Try either of these:

https://github.com/rustify-emacs/fuz.el/blob/master/helm-fuz.el#L228
https://github.com/emacs-helm/helm/blob/master/helm-utils.el

And I'm considering using it in company-sort-by-occurrence, to make sure 
that flex sorting is at least semi-honored there (or create a variation 
of that transformer). For that to happen, the possible score values and 
their meanings will need to be documented, though.

The main scenario (and source of the completion-score property) I have 
in mind is not related to fido-mode or flex, but the users can always 
put flex into completion-styles by default, which affects company-capf.
