How much surfactant in percentage is in cornerstone plus?

Unfortunately without getting ahold of manufacturer specs (which is almost impossible considering they do not have to disclose inactive ingredients), this will be very hard to answer.

Much like other "fully loaded" glyphosate products it is pushed as not needing an additional surfactant and in most cases you can get away with that. However, you should always include ammonium sulfate or another type of water conditioning agent with all glyphosate products.

For reference, regular cornerstone (without surfactant) calls for the use of 1 quart per 100 gallons of water nonionic surfactant.
