I doubt that Snape had any ulterior motive for leaving the book in the 
classroom. If it indeed belongs to him, he may have placed it in his 
classroom as a reference and forgot to remove it when he became DADA 
professor. It was purely chance that Harry received that particular 
book. It could have just as easily gone to Ron. Or, another 
hypothesis, Dumbledore could have told Harry that Snape wasn't going 
to be potions professor and Harry would have purchased a book for the 
class in advance. Snape had no control over how Harry was to gain 
possession of it, therefore, I don't believe that he intended for him 
to have it.

IMO, Snape was genuinely shocked to learn that Harry knew the spell he 
used to attack Draco and realized that Harry had found the old book. 
Harry went to great lengths to disguise/hide his book and yet Snape 
didn't buy it. He knew differently. If Snape had actually engineered 
the circumstances for the book to go to Harry, I don't believe that he 
would made any reference to it, nor, punished Harry for lying about it.
