Scripting for Excel VBA 5 level sort

I have part of a complex sort done.  I'm attaching the spreadsheet and code so far.  I basically need a 5 level sort.  Categories with a minus "-" in front (col A) of them expand to contain sub categories -- they can also have a plus "+" in front of them indicating that they are rolled up.  If there is a space " " in column A that indicates a category with no subcategories.  I need to sort the sub categories within the categories and then sort every category against other categories.  I have that part done.  The complexity comes because there can be sub sub categories, or another level of category within the sub category.  In that case I want those categories sorted within the sub category.  So I somehow need to test both column A and column B for the +, - or space.  So I'm wondering first, is my code the best way to do this (It does work for sub categories and categories) and second, how to incorporate the testing for sub sub categories.  I'm using Excel 2010.  Thanks

Set subsign = Range("B3")

While r.Row <= lastrow
    If sign.Value <> "" Then
        s.Formula = catcount + 0.1
        r.Formula = r.Offset(0, -2).text
        catcount2 = catcount
        catcount = catcount - 1
    Else   'populate cell with value in cell above
        r.Formula = r.Offset(-1, 0).text
        s.Formula = catcount2
    End If
