Looping will not work because the length and indexing of "Items" changes each time you remove an element. You must remove all of the elements simultaneously,
Items(orderedCount<3)=[];

As I mentioned, and as my example showed you, this should be done without a loop. The single line
Items(orderedCount<3)=[];
will do the whole job.
