He didn't get his Scar from a Water Buffalo. The Book called: The Tale of Two Brothers explains that he got his Scar as a young cub with Mufusa in an accident in the Elephant Graveyard... A tragic tale.. He then tells everyone from now-on to call him "Scar" to remind him of his arrogance.
Edit: You were right. As taken from Disney Wiki:
In A Tale of Two Brothers, the young hyenas appear at the beginning where they surround a helpless Rafiki who had just arrived in the Pride Lands. King Ahadi comes to the rescue just in time, with his sons Mufasa and Taka (Scar), and demands that the hyenas leave. The hyenas appear again later, where Shenzi advises Scar to make himself look good by making Mufasa look bad. Scar decided to incite a Cape Buffalo called Boma to fight Mufasa. The plan did not turn out well, and Scar's eye was wounded by the buffalo herd in the process, hence the nickname "Scar".
