Queries :: Sequential Numbering Within A Query

I've taken on the task of transitioning excel reports (and their format) to a database. One report summarizes all the parts of a piece of furniture, and the order of the machines each part goes to.It looks similar to this:

Part# Part Name Machines/Operations
M7264Top Panel 112114116120121325216
M7265Under Top Panel 112114116120121
M7266Base Assembly 411325216311310312316

The table this comes from has both operations and setups, so I used a query to filter only the operations.The query (qryOperations) result looks like this:

PART NUMBEROPERATION ORDER
M7264 112 2
M7264 114 4
M7264 116 6
M7264 120 7
M7264 121 8
M7264 325 9
M7264 216 10
M7265 112 2
M7265 114 4
M7265 116 6
M7265 120 8
M7265 121 9

i need to add sequential numbering (1,2,3,4...) to each line of the qryOperations and use the sequential numbering as the column header.How do I add sequential numbers to the query, that restart after each change in part number? I can do this in a report easy enough, but not a query.This is the SQL of the query I need to have the sequential numbers in...

SELECT tblparts.[PART NUMBER], tblOperationCodes.MachineCode, tblOperationsList.Order
FROM tblparts INNER JOIN (tblOperationsList INNER JOIN tblOperationCodes ON tblOperationsList.OperationCode = tblOperationCodes.OperationCode) ON tblparts.[PART NUMBER] = tblOperationsList.[PART#]
WHERE (((tblOperationCodes.Function)="O"))
ORDER BY tblparts.[PART NUMBER], tblOperationsList.Order;
