Rails spinoffs - May 2006 - Sorting a hash

Quick Prototype.js hash question.

Given:
MyHash = {"Alpha" : {name:"Foo",val:3},
"Delta" : {name:"Bar",val:2},
"Beta" : {name:"Baz",val:4} }

I want to display this set ordered by key - Alpha,Beta,Delta and by  
val - 2,3,4
Prototype.js helps with the hash:
$H(MyHash).keys().sort() will give me Alpha, Beta, Delta
but I''ve not figured out how to extract the keys in sorted order  
"Delta,Alpha,Beta" according to val.

Thoughts?

D''oh. Easy answer with sort:

$H(MyHash).keys().sort(function(a,b) {
		return MyHash[a].val - MyHash[b].val;
	});
