Deadly encounter
I use a HTML encounter calculator by John Dells, the Mathinator - his claim to fame, not my addition. I plugged in the character levels (assuming that the orc's elite stats balanced out the party's high values and gear) and this was its opinion:
Difficulty: Deadly
Advice to party: Run Away!
I would tend to agree with this opinion and that's not even taking into account the fact that they got ambushed. With the amount of damage the orcs were dishing out, the party had hardly any time to work on tactics, even bad ones.
In addition, I have noticed that high strength melee characters can really chew up the opposition if they get toe-to-toe. One party that I play in recently got TPKed by a high strength demon (whose CR was also too high for the party level I suspect).
A more balanced encounter would have been 4-5 level 3 orc barbarians. While it is still rated as Very hard and advises the players to Pull out all the Stops, at least the glitterdust and color spray spells would have been more effective.
