I bet most kernels don't support having a #! line in a script that points to another script that has another #! that points to another thing. You see how that could quickly get rather convoluted.

Unfortunately, when I try to do that myself to test it, rather than a nice clear error message telling me not to be such a clever prick, I get errors that look like my Perl script is being interpreted by something other than perl but I am, so far, at a loss as to what that other thing is.

When I ran "strace script" to figure out what other thing is trying to interpret my Perl code, I got "exec: Exec format error" from strace.

So, one answer for the OP is to write this simple wrapper in a compiled language so that the wrapper doesn't need a #! of its own.
