A Visual Studio 2005 macro that sorts the using statements.

Sub SortUsingStatements()
     Dim selectedText As TextSelection
     Dim line As String
     Dim out As String
     Dim nonSystem As String
     Dim systemLines As String
     Dim systemOnly As String

     selectedText = DTE.ActiveDocument.Selection
     Dim lines() As String = Split(selectedText.Text, vbLf)

     System.Array.Sort(lines)

     For Each line In lines
         If line.Contains("System;") Then
             systemOnly = line + vbLf

         ElseIf line.Contains("System") Then
             systemLines = systemLines + line + vbLf

         Else
             nonSystem = nonSystem + line + vbLf
         End If
     Next
     out = systemOnly + systemLines + nonSystem
     selectedText.Insert(out)
 End Sub
