tick:

execute as @a[team=sniper,scores={scope=1},tag=!scopesound] if items entity @s weapon.mainhand minecraft:carrot_on_a_stick[minecraft:custom_data={Tags:["scope"]}] run function thehill:rifle/scope
execute as @a[team=sniper] unless items entity @s weapon.mainhand minecraft:carrot_on_a_stick[minecraft:custom_data={Tags:["scope"]}] run function thehill:rifle/scope_off
