Macro Sort A-Z, Exclude Some Text So It's Not Sorted

I've setup a macro button to sort some stockpile items from A-Z so entering quantity on hand can be done more easily. Each cell is a drop-down selection so at various times, there can be different stockpile items in the list, thus why, I setup a macro to quickly sort the list.

However, I've got some text (Select Stockpile Item) that I wish not to be included in the A-Z sort as this might put items starting with T or later at the end of the sort.

Sub SortMySpecialStockpileA2Z()
If MsgBox("Are you sure?", vbYesNo + vbQuestion) = vbNo Then
Exit Sub
Else
Range("K4:L110").Select
ActiveWorkbook.Worksheets("MyStockpile").Sort.SortFields.Clear
ActiveWorkbook.Worksheets("MyStockpile").Sort.SortFields.Add Key:=Range("K4") _
, SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
With ActiveWorkbook.Worksheets("MyStockpile").Sort
.SetRange Range("K4:L110")
.Header = xlNo
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
End If
End Sub
