Tudo bem, fiquei meio enjoado com essa pergunta. Eu escrevi essa macro, classifica em ordem crescente, divide o intervalo não em branco no meio (arredondado para cima) e aplica duas escalas de cores. Modifique como quiser.

inthalf = intcount / 2
inthalf = Application.WorksheetFunction.RoundUp(inthalf, 0)
'Do first half

Set rng1 = Range(Cells(1, 1), Cells(inthalf, 1))
' Add a 2-color scale.
