I too have used similar.
Usually a polygon/way with one school on it and then a node inside it 
for the other school, or schools if more than one.

On one occasion I have separated then into 2 separate ways, I am certain 
that some of each area will be shared from time to time, but it seams to 
be a good compromise. Every other time I have not had any reasonable 
chance of doing this.

Most people would consider amenity=school to be a land use, along with 
other tags such as leisure=recreation_ground.
