Queries :: Tracking Database - Retrieve Top 100 Records

I am working on a project where I am creating a database that tracks open orders (old and new orders that still need to be billed but haven't been billed for one reason or another).

I have my "Master" table built and now I need to create 2 queries, one query retrieves the Top 20 orders based on value and that are older then 30 days and the second query is to retrieve the Top 100 orders based on the same criteria but the Top 100 query should not include the orders that appear in the Top 20 query.

My Top 20 query is below

SELECT TOP 20 MASTER.COMBO, MASTER.[Customer Name], MASTER.Status, MASTER.CCD, MASTER.Area, MASTER.[Order Type], MASTER.[Order Value], MASTER.AGE, MASTER.ANALYST, MASTER.COMMENTS
FROM MASTER
WHERE (((MASTER.AGE)>=30))
ORDER BY MASTER.[Order Value] DESC , MASTER.AGE;

I have tried multiple ways to do the Top 100 query and exclude what is returned in my Top 20 query but so far no success.
