Funnelback only supports result sorting on a single key.
If you wish to sort on more than one key then you'll need to generate a sort field that concatenates the fields you wish to sort on together (in a way that will sort alphabetically) in your metadata and sort on that. If exporting from a DB it's usually quite straightforward to generate an extra sort field in the DB view that you are indexing.
e.g. for the above example you might have two fields courseName and courseDate
You'd need to generate an additional field like courseSort that had the courseName+courseDate values concatenated.
Note: for the dates to sort numerically you'd need to pad the single digits otherwise you'd get a sort like 1 11 12 2 for the dates.
