how would you want them to be sorted?

you could write a callback function and use that function in the nameCompareFunction attribute.

Just by name is fine.  Currently they do not come in that way and i want to guarantee it does.

normally they should... could you post your mxml please?

an example for reverse sorting would be:

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
      <![CDATA[
            public function compareFileNames(name1:String, name2:String):int{
                  if(name1 > name2)return -1;
                  else if (name2 > name1) return 1;
                  else return 0;
            }
      ]]>
</mx:Script>
    <mx:Button label="Up" click="fileList.navigateUp();"
        enabled="{fileList.canNavigateUp}"/>
    <mx:FileSystemList id="fileList" nameCompareFunction="compareFileNames"/>
</mx:WindowedApplication>
