No, this path
       /path/to/scripts/$host$fastcgi_script_name;
may be on any host.

In your case you need probably this:

      fastcgi_param SCRIPT_FILENAME /$host$fastcgi_script_name;

Also, this

       if ($http_x_forwarded_for ~ "(?:^|,)\s*(\d+\.\d+\.\d+\.\d+)\s*$") {
           set  $addr  $1;
       }

       fastcgi_param REMOTE_ADDR     $addr;

means that anyone may forge his address.
