Flavored Project Property Page Sorting

Is there a way to alter the sorting of project property pages in a flavored project

My flavored project extends FlavoredProjectBase and implements GetProperty to register a configuration independent property page.

protected override int GetProperty(uint itemId, int propId, out object property)
{
    if(propId == (int)__VSHPROPID2.VSHPROPID_PropertyPagesCLSIDList)
    {
        ErrorHandler.ThrowOnFailure(base.GetProperty(itemId, propId, out property));
        property = String.Format("{0};{1}", typeof(PropertyPage).GUID.ToString("B"), property);
        return VSConstants.S_OK;
    }
    return base.GetProperty(itemId, propId, out property);
}

I try different sorting of the GUIDs in property object but that doesn't seems to affect the sorting of the property pages.

I want that my custom page "Ice Builder" appears bellow "Build Events" and not bellow Signing
