I believe you can specify a version like this:

loExcel = CreateObject("Excel.Application.11")  && 2003
loExcel = CreateObject("Excel.Application.12")  && 2007
* from http://en.wikipedia.org/wiki/History_of_Microsoft_Office

I've never tried it on a machine with multiple versions of Office (or components) installed. I don't know how reliable it is, considering which version may have been registered last and/or updates installed by Microsoft Update.
