Sorting Numeric Dimensions

In DeepSee we have a field that is numeric but is used as a dimension. In DeepSee it sorts this field in the following order. 10, 11, 15, 2, 3, 5, 6, 8, 990. Is there a way to have DeepSee sort it numerically instead of treating it like a character field? We would want to see it show up in the dimension as 2,3,5,6,7,10,11,15,990.
