I am fairly certain that anyone can identify any type of spell using spellcraft. A stable boy with 5 ranks would still have about a 50% chance of identifying a magic missile spell or cure light wounds.
That said, unless you rule otherwise I automatically fail, as the rules are quite explicit that "you must be able to clearly see the spell as it is being cast."
See this thread in which people no smarter than we verify my vague suspicions:
