Not sure, I'm afraid. Jaime Leralta in his monumental history and legend of royal names doesn't give a source for when Alfonso gained the nickname. In his lifetime he was honoured as el rey sabio, the wise king and it seems to have stuck. I suspect the answer is lost in the midst of times, and such things are usually by popular acclaim.
A much better nickname than some of the ones Spain has given to their leaders: Juana "la loca" (the mad) or Carlos "el hechizado" (the bewitched) were both known as that during their lifetimes.
