Order workdays in transition status

Hi,

I need to order workdays in transition status.

But Order function can only order set : Order(Set_Expression, Value_Expression)

So how can i have the display result ordered of this measure by workdays ?

CASE WHEN [Measures].[Transitions from status] > 0 THEN
[Measures].[Workdays in transition status] /
[Measures].[Transitions from status]
END
