Here's a doc excerpt that explains it very clearly. If you need more details just ask.


To specify a sort order for a recordset object

Construct a new recordset object (or prepare to call Requery for an existing one).


Set the value of the object’s m_strSort data member.
The sort is a null-terminated string. It contains the contents of the ORDER BY clause but not the keyword ORDER BY. For example, use:

recordset.m_strSort = "LastName DESC, FirstName DESC";

not

recordset.m_strSort = "ORDER BY LastName DESC, FirstName DESC";

Set any other options you need, such as a filter, locking mode, or parameters.


Call Open for the new object (or Requery for an existing object).
The selected records are ordered as specified. For example, to sort a set of student records in descending order by last name, then first name, do the following:

// Construct the recordset
CStudentSet rsStudent( NULL );
// Set the sort
rsStudent.m_strSort = "LastName DESC, FirstName DESC";
// Run the query with the sort in place
rsStudent.Open( );

The recordset contains all of the student records, sorted in descending order (Z to A) by last name, then by first name.
