[vbnullchar]

I need to sort this array by [score].. anyone?

[code]Array (
  [1] => Array ( [id] => 1 [title] => Acoustic - Pop [score] => 4 )
  [2] => Array ( [id] => 2 [title] => Ballad [score] => 1 )
  [3] => Array ( [id] => 3 [title] => Bossa Nova [score] => 3 )
  [4] => Array ( [id] => 4 [title] => Chillout/Lounge [score] => 2 )
