It will probably work if /bin/ksh is a link to zsh. This is common on a lot of our Linux boxes here.

What CFA J & I are telling you is that the best practice is to use the magic at the top of your script. But you do not have guarantees what shell you will invoke, especially when the code is ported. So, on the internet, that becomes very true - like porting into a black hole. So, #!/bin/ksh may not mean what you think.
