If I have an array of hashes, eg

[{'name'=>'Anna', 'score'=>11}, {'name'=>'Bryce', 'score'=>7}, 
{'name'=>'Chris', 'score'=>9}]

Is there an easy, Ruby-idiomatic way to sort this array by the 'score' 
elements of each hash? eg so I get

[{'name'=>'Bryce', 'score'=>7}, {'name'=>'Chris', 'score'=>9}, 
{'name'=>'Anna', 'score'=>11}]

Thanks,
Tim Bates
