How to add a label based on dense rank value [duplicate] - tsql

Question

This question already exists:
Cannot when add ORDER BY in a CTE
Closed 9 months ago.
Is there any way I can reference the inner dense rank results and give them appropriate labels like I am trying to do? It seems like in T-SQL I just can NOT do an "Order by" in an inner query, it is producing an error like:
The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.
But then how do I attach appropriate labels to the dense rank results in the code below?
WITH basequery AS (
SELECT c.baseentityid,
c.team,
c.providerid,
-- rank() OVER (PARTITION BY c.baseentityid ORDER BY c.version DESC) AS rn,
t.vaccinedate,
t.vaccine,
t.vaccinesource,
t.num
FROM vr.child_registration c
CROSS APPLY ( VALUES (c.bcgsource,c.bcgdate,'bcg',1), (c.opv0source,c.opv0date,'opv0',2), (c.penta1source,c.penta1date,'penta1',3), (c.pcv1source,c.pcv1date,'pcv1',4), (c.rota1source,c.rota1date,'rota1',5), (c.opv1source,c.opv1date,'opv1',6), (c.penta2source,c.penta2date,'penta2',7), (c.pcv2source,c.pcv2date,'pcv2',8), (c.rota2source,c.rota2date,'rota2',9), (c.opv2source,c.opv2date,'opv2',10), (c.penta3source,c.penta3date,'penta3',11), (c.ipvsource,c.ipvdate,'ipv',12), (c.pcv3source,c.pcv3date,'pcv3',13), (c.opv3source,c.opv3date,'opv3',14), (c.measles1source,c.measles1date,'measles1',15), (c.tcvsource,c.tcvdate,'tcv',16), (c.ipv2source,c.ipv2date,'ipv2',17), (c.measles2source,c.measles2date,'measles2',18)) t(vaccinesource, vaccinedate, vaccine, num)
