I understand how to sort an array with a single value but how can I  
sort an array w multiple values : [integer\_value1, float\_value2]

an\_array = [[123, 42.50], [245, 25.45], [389, 32.69] ]

wich should give (sorting on the 2nd value)

sorted\_array =\> [[245, 25.45], [389, 32.69], [123, 42.50] ]

thanks for your help
