The NotesUIDocument class is designed to work with the interface elements (what is being displayed) of a document.  Because of this, the value you retrieve from a field is what is being displayed to a user.
If you are designing a new form, a workaround you can use is to make the aliases numerical such as:

  Dim ws As New NotesUIWorkspace
  Dim doc As NotesDocument
  Dim uidoc As NotesUIDocument
  Dim desiredresult As Variant
  Set uidoc = ws.CurrentDocument
  Set doc = uidoc.Document
  desiredresult = doc.GetItemValue("Status")
  Select Case desiredresult(0)
  Case "1"
       ...
  Case "2"
       ...
  Case Else
       ...
  End Select
