If you want to make it work you need to remove "2&>1" because with that further redirection $? and status is always 0... and the scripts just prompts the first line of the password file

@readonlymaio I've changed it back

it was wrong redirection, should be:
7z x -p$i $1 -aoa >/dev/null 2>&1
vs
7z x -p$i $1 -aoa >/dev/null 2&>1
