Delete that line - it does nothing useful here. (It does no harm, other
than being a distraction.)

Change that line to be just

    fastcgi_param  SCRIPT_FILENAME $document_root;

"alias" is a bit funny. In this context, it means that $document_root
corresponds to the file on the filesystem that you want the fastcgi
server to process.

I'm a bit surprised that the current version works -- perhaps your php
config does not have

  cgi.fix_pathinfo=0

and so takes more than one guess at the file to process.

Delete.

Change to remove $fastcgi_script_name, just like the previous case.

Here, most likely php is not involved, and your fastcgi server just tries
to process SCRIPT_FILENAME, which does not name a real file right now.

I think that the explanations are above, along with the one necessary fix
(for cgi/pl) and the one strongly suggested fix (for php).

Good luck with it,
