"Tech Companies That Won't Delete Your Information Services with the highest scores have the worst policies"
I read this as 20 is worse than 1.
Maybe something along these lines, explicitly explaining 1 is the worse.
"Tech Companies That Won't Delete Your Information Services. Those with the highest rank have the worst policies. A rank of 1 is the worst offender"
I think this is somewhat a problem of English missing a term that unambiguously means "1 is highest".
