It was clear enough to work out goals for as the total, 10, will be the same as the total number of goals against. There are some teams, such as team A, for which there is only one combination of results ending up in their number of points (for example, in this case 3 points can be 1 win, 1 loss). Only two teams drew, so they must have drew against each other, and, starting by looking at a 1-1 draw, allowed me to deduce scores (see attached spreadsheet for answers).
