I faced a similar problem some time ago what I did was to add an array property (I did it on the form for I was planning to put it in the class later, which then I forgot until now that you mentioned..), I called PageToPageOrder, then in the init you can put code like this:

local lnPage, loPage

lnPage = 0
DIMENSION this.PageToPageOrder(this.PageCount, 2)

FOR EACH loPage IN this.Pages FOXOBJECT
	lnPage		= lnPage + 1
	this.PageToPageOrder[loPage.PageOrder, 1] = lnPage	&& Page[PageOrder, 1] returns PageNumber for a PageOrder
	this.PageToPageOrder[lnPage, 2] = loPage.PageOrder	&& Page[PageNumber, 2] returns a PageOrder for a PageNumber
ENDFOR

So now somewhere else where I needed I can do, for example:

lnActivePage = thisform.myPageFrame.PageToPageOrder[thisform.myPageFrame.ActivePage, 1]
loActivePage = evaluate('thisform.myPageFrame.page'+transform(lnActivePage))

In your example you would change

IF MyPageFrame.ActivePage = 3
...

to

IF MyPageFrame.PageToPageOrder[MyPageFrame.ActivePage, 1] = 3
...
