The party is returning to an area of the world where they started their adventuring years. The area is known for its vicious orc raiders. The party was on the receiving end of these raids many times.
Run it like you did all those other raids, then. If they weren't sneaking up in carefully-grouped waves backed by archers hidden atop the battlement-like heights of sheer cliffs, then don't have these guys be doing that. As you said, it's a bunch of punk orc raiders -- have them act like all those other orc raiders did. If those orcs attack in a ragged mass charge, then so be it -- they'll eat a
fireball or
flame strike, should the spellcasters decide to use such on some bad guys.
If they don't survive long enough for all the PCs to get an action, well, they don't. That's just what happens to low level mooks that attack high level types (I imagine spellcasters would be most likely to take out a whole group -- without Combat Reflexes & crazy enemies, Superior Cleave, or being completely surrounded by 2 ranks while wielding a spiked chain, fighter types usually have trouble killing a dozen in one round).
Or, hey, maybe the wizard will relish the chance to beat some orcs to the ground with their staff or whatever -- a 17th level wizard does get iterative attacks, after all. Then everyone can just beat the orcs down.
If you really want to give everybody a chance to slaughter some mooks, use more than a dozen; have it be a BIG raiding party. Depending on the size & composition of your party (e.g., if you have a sorcerer, a wizard, and a cleric of the God of Blowing Stuff Up, you might want more), use two, three, or four dozen (coming from a couple-three directions). Then the cleric can
greater command/flame strike one bunch, the wizard or sorcerer can
fireball/ice storm/chain lightning one lot, the fighter can get surrounded and Great Cleave through a pack, the rogue can bust out a few sneak attacks, etc.
Heck, you could pitch to the PCs' specialties. If the wizard loves
lightning bolt, send a bunch of orcs at 'em down a gully (all lined up). If one PC is an archer, go ahead and put a dozen orcs w/longbows on the otherside of some gully -- the PC can slaughter 5 a round while the orcs try to get lucky with one hit. If one PC is some sort of jumping & tumbling machine (say, a monk), put one orc shaman on the far side of that gully, with some minions guarding him, so the monk can leap across, tumble through the minions, and deliver the Spring Attack-Improved Trip-Stunning Fist-2d8 combo o' doom on him. Etc.
Let the PCs get attacked by a dozen orcs, slaughter them, and then learn that a large raiding party has taken over a nearby fort/manor/hamlet. Let the PCs descend like the wrath of 17th level characters on 'em and chop 'em up.
Then on with the level-appropriate quest.
