I have another question about sorting numbers in a listview

I am trying to sort numbers in my listview from smallest to largest using array.sort but it is not working.

Here is what I have, Thanks

For i = 0 To lvwScores.Items.Count - 1
Dim currentVal As Double = lvwScores.Items(i).SubItems(6).Text
Dim index(0) As Double

index(0) = currentVal
Array.Sort(index)
ListBox1.Items.Add(currentVal)
