It looks as though you've entered the 090 and 099 as text in order to get the leading zeros (or is it zeroes?).
Use a custom number format: Format, Cells, Custom. Enter
000 as your number format. Now, when you enter 9 in the cell it will display as 009, 26 will display as 026, and so on... and Excel will treat it as a number instead of text.
Should solve your problem!
