Sorting / Ordinal for dimension status attribute

I have a dimension (vehicles) which carries a Status attribute. The various values that can exist in a status have a somewhat nature flow to their order (i.e. New, In Service, Sold). When displaying data grouped by this status value, I'd like to order my groupings by this natural flow. What is the best way to represent an ordinal for a given dimension value?

You could add a report sequence attribute to the dimension.

Thanks, I had figured it might be as simple as adding new attribute, but I didn't know if a different method was more accepted.

Thank you again.

Would like to give a tip on creating a sequence and its data type. It is more flexible to use a decimal sequence data type then use a integer data type. For example if you already have a sequence number 1, 2, 3 and latter down the road business user wants to see "rebuilt" between "new" and "In Service" value, then giving a sequence value of 1.5 would prevent any re-sequencing if you used decimal data type.

seq#, value
1 , New
1.5 , Rebuilt
2, In Service
3, Sold
