You can try to sort first by the least significant column, and then by the most significant column. I used this a while ago in some spreadsheet that didn't have multi-column sort capabilities, but this method relies on the assumption that data is not shuffled about more than is absolutely required for sorting - an assumption I can not vouch for. You might try it, though.

Another possibility is to add another column, which contains the combined key - with the same expression you would use for an index expression (i.e., convert everything to type "C", and use a fixed length).
