It is very likely that the data type of the field is not numeric. It is a text sorting that you are showing. Are you storing more than just a number in that field? If not, change it to a numeric field. Otherwise, you can fake the numeric sorting by storing a 3 digit number: 001, 002, 003 ,004 and so on to to 488. Make sense?
