Using commands on command blocks (specifically chain ones) to change scoreboard values. Specifically ones using execute commands.

Sorry I typed the command in wrong to this comment. It is execute @e[type=Zombie,rym=88,ry=90] ~ ~ ~ scoreboard players set @e[c=1] rotation 90
To my understanding this should set any zombie with a rotation minimum of 88 and a maximum of 90 to a score of rotation equals 90
Tried your setup.
[18:36:46] [Client thread/INFO]: [CHAT] [Zombie: Set score of rotation for player redstonehelper to 90]
Use a better selector for the second @e.
More specifically execute @e[type=Zombie,ry=90] ~ ~ ~ scotreboard players set @e[c=1] rotation 90
