Comparar archivos en desorden

Me la pones un poco dificil. Se me ocurre que talves utilizando Tablas Dinámicas Consolidadas (Herramientas-Informe de Tablas Dinámicas) y luego seleccionas rangos consolidados.
También prueba con este código que me encontré:
Sub CopyRangeFromMultiWorksheets()
Dim sh As Worksheet
Dim DestSh As Worksheet
Dim Last As Long
Dim CopyRng As Range
With Application
.ScreenUpdating = False
.EnableEvents = False
End With
' Delete the summary sheet if it exists.
Application.DisplayAlerts = False
On Error Resume Next
ActiveWorkbook.Worksheets("RDBMergeSheet").Delete
On Error GoTo 0
Application.DisplayAlerts = True
' Add a new summary worksheet.
Set DestSh = ActiveWorkbook.Worksheets.Add
DestSh.Name = "RDBMergeSheet"
' Loop through all worksheets and copy the data to the
' summary worksheet.
For Each sh In ActiveWorkbook.Worksheets
If sh.Name <> DestSh.Name Then
' Find the last row with data on the summary worksheet.
Last = LastRow(DestSh)
' Specify the range to place the data.
Set CopyRng = sh.Range("A1:G1")
' Test to see whether there are enough rows in the summary
' worksheet to copy all the data.
If Last + CopyRng.Rows.Count > DestSh.Rows.Count Then
MsgBox "There are not enough rows in the " & _
"summary worksheet to place the data."
GoTo ExitTheSub
End If
' This statement copies values and formats from each
' worksheet.
CopyRng.Copy
With DestSh.Cells(Last + 1, "A")
.PasteSpecial xlPasteValues
.PasteSpecial xlPasteFormats
Application.CutCopyMode = False
End With
' Optional: This statement will copy the sheet
' name in the H column.
DestSh.Cells(Last + 1, "H").Resize(CopyRng.Rows.Count).Value = sh.Name
End If
Next
ExitTheSub:
Application.Goto DestSh.Cells(1)
' AutoFit the column width in the summary sheet.
DestSh.Columns.AutoFit
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
End Sub
