This should be possible using a custom callback function with usort.

I had thought about doing the data manipulation and then sending it to a new table and then querying that using ORDER BY but thought it must be possible to do the sorting in php so I didn't have to query the database twice. Out of interest which method is more programmatically correct?
Neither method is more "correct" than the other, although I prefer to
sort data directly from MySQL where possible, and on a large data set
you will find this more efficient. In this case, you are doing
subsequent manipulation on the data, so sorting in PHP is more
appropriate.
