You can change the line: 
$_->[0] <=> $_->[1]

[download]
to 
$_[0] <=> $_[1]

[download]
or 
@_->[0] <=> @_->[1]

[download]
and even insanely to 
@{[shift]}->[0] <=> @{[shift]}->[0]

[download]
And it will work.

The last last solution is highly perl implementation dependent, it will not work if the order of evaluation changes in the future. I came up with it just to see if I could compare two shift's directly for fun. And yes it works. :)
