WAD - Map Item - How to modify class ranges?

I am trying to create a template in WAD, and want to include a map item to display data by country. I am using a CS map renderer, and if I use the default class definitions, everything is fine, but I want to define my own ranges. I have specified that I want to use three classes, and I'm trying to set the values in the "List of Class Limits" by setting the upper class limits. My data is percentages, so I want to create three classes (< 0%, 0-5%, >5%).

I would think that the right way to do this would be to create three classes and specify two upper class limits of 0 and 5. No matter what I try, it seems that the template just picks it's own ranges. Am I specifying the ranges incorrectly, or is this just not possible?

Here is the resulting XHTML for my map item:

                <bi:MAP_ITEM name="MAP_ITEM_1" designheight="400" designwidth="928" >
                    <bi:WIDTH value="928" />
                    <bi:HEIGHT value="400" />
                    <bi:MAPLAYER_LIST type="ORDEREDLIST" >
