You can remove one problem by eliminating the use of commas. Since EXCEL
generally sorts using the ASCII table, the comma will certainly screw up the
sort. You can experiment with the ASCII table by using EXCEL.

In B1 enter 1
In B2 enter 2
Fill in 1,2,3 up to 128
Then in A1 enter the formula =CHAR(B1)
copy down.

This will display the logical sort parameters.
