Assuming you want to stay in Excel, here's VBA code which I think will do
what you want:

Public Function LargestValueInString(str As String, min As Integer, max As
Integer) As Integer
Dim match As Variant
Dim val As Integer, hival As Integer
hival = -1

   With CreateObject("VBScript.RegExp")

      .Pattern = "[0-9]+"
      .IgnoreCase = True
      .Global = True

      For Each match In .Execute(str)
         If Len(match.Value) < 5 Then  ' if you want bigger values you'll
need doubles not ints
            val = CInt(match.Value)
            If (val >= min) And (val <= max) And (val > hival) Then hival =
val
            End If
      Next
   End With

LargestValueInString = hival
End Function

I've attached a spreadsheet with the code and an example.  If it doesn't
make it through to you, let me know and I'll send it offline.  And it's in
Excel 2010, which is what I happen to have, but I guess I can save it in
another format if you want.
