Length of a numeric variable---already imported

Hi,
I imported an excel file into SAS 9.3.
One of my variables is INCOME.
Running a proc freq, my income is listed out of order, according to the first number, so for instance, here is an example of my output (attached):



Do I need to re-import the excel datasheet with some kind of length statement, or is there another way to sort this variable, so that, 96 is listed first, etc.?

Thanks!
