 +Current Behavior:

 +    Sort regular:

 +      [0] =>
 +      string(2) "01"
 +      [1] =>
 +      string(1) "1"

 +      [4] =>
 +      int(3)
 +      [5] =>
 +      string(2) "03"
 +    }
 +    Sort numeric:
 +    array(6) {
 +      [0] =>
 +      string(2) "01"
 +      [1] =>
 +      string(1) "1"
 +      [2] =>
 +      int(2)
 +      [3] =>
 +      string(2) "02"
 +      [4] =>
 +      string(2) "03"
 +      [5] =>
 +      int(3)
 +    }
 +    Sort binary:
 +    array(6) {
 +      [0] =>
 +      string(2) "01"
 +      [1] =>
 +      string(2) "02"
 +      [2] =>
 +      string(2) "03"
 +      [3] =>
 +      string(1) "1"
 +      [4] =>
 +      int(2)
 +      [5] =>
 +      int(3)
 +    }
 +
 +Changed Behavior:
 +
 +    Sort regular:
 +    array(6) {
 +      [0]=>
 +      string(2) "01"
 +      [1]=>
 +      string(2) "02"
 +      [2]=>
