Yes, setting the %ENV values you want to use within the program is exactly how to untaint them. Your method is a little more elaborate than I would usually use, but it looks fine to me.

Rather than arrays, I would probably work directly with the strings. The arrays have some nice features, though.

You can avoid the need to detaint PATH by using the absolute location of /bin/ls, which is unix standard.
