I am getting the following warnings. I understand why they are appearing ( Use of implicit split to @_ is deprecated ) but I'm not sure what the best way to rewrite the code. Suggestions?

Use of implicit split to @_ is deprecated at ./tie-listkeyshash-test.p
+l line 31.

And the code: 
my @paths = (
             "C:\\foo\\bar",
             "C:\\foo\\bar\\baz",
             "C:\\car",
             );
print "paths",  Dumper(\@paths);
@paths = sort { scalar (split (/\\/ , $b)) <=>
                scalar (split (/\\/ , $a))     } @paths;
print "paths",  Dumper(\@paths);

Update: I just did the following: 
sub dir_component_count($) {
    my $path = shift;
    my @components = split /\\/ , $path;
    return scalar (@components);
}

@paths = sort { dir_component_count($b) <=>
                dir_component_count($a)     } @paths;
