I offer another right-to-leftification of your example: 
%h = map { $_->[0], $h{$_->[0]} } [ sort { $a<=>$b } keys %h ];

Do you find it more readable? Personally, I found the line breaks and indentation that other posters provided was more helpful in adding readability than making the direction consistent. But if you're going to do it on one line, it is helpful to have things go one direction.

Update: is this better or worse? 

%h = map { $_, $h{$_} } map { $_->[0] } [ sort { $a<=>$b } keys %h ];

Take the keys, sort them, take the first one, and make the hash from the hash entry.
We're not really tightening our belts, it just feels that way because we're getting fatter.
