Looks like a typo, further down in perlrun(1) there is

                #!/usr/bin/perl
                eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
                        if $running_under_some_shell;

and this one is what is used by scripts I have in many /usr/bin Perl 
scripts.  But the utility of it totally escapes me.  Your solution using 
perl -x has the advantage of working, so go for it...
