The description of Gruumsh in that Orc flavor text makes it feel like they are moving him into more "Chaotic Neutral" territory: so in AD&D terms you could logically have CE, CG, CN, or even True Neutral Gruumsh religious groups. Which goes a long way to refine Orcs cosmically.They're certainly more "civilized" than they've ever been depicted before.
Personally, I've always (like, since the mid-eighties) portrayed them as generally from a society that has a certain sense of honor, but reveres the strong, and has a tolerance for violence that your average human society struggles to understand. I've always felt that calling anyone "inherently evil" is primarily propaganda. That's how I've played it, anyhow. These orcs won't be all that different to mine, really.
