Here's what I've observed/tested so far for Crit/Bash/Orbs in DotA2. Fairly obvious, but the 3 no longer interfere with each other compare to DotA1.
DISCLAIMER: DotA2 being a beta that it is, sometimes things may change and I don't bother re-test everything each patch, so if something changed and I didn't notice, feel free to tell me about it.
Priority of Orb(Unique Attack Modifiers):
Going from the top down are highest to lowest in priority.
Crit:
When multiple critical occurs, the highest multiplier take priority, end of story. (Yes, it's that simple, hooray)
Monkey King Bar's Truestrike is no longer a critical in DotA2, feel free to never again discuss whether it 'stack with X'
By request of shalafi, some bonus damage's interaction with crits (Lifesteal will heal you for the final damage):
NOTE: The orb that says Yes on Lifesteal require you to have some way of gaining the lifesteal that's not an orb (Vlad aura, Skeleton King)
Bash:
Multiple bashes add the damage bonus together, regardless of melee or range.
Bashes add to your damage, and thus you can lifesteal from them.

Type | Example |

Oldest orb in inventory | Morbid Mask, Desolator |
Special exceptions to this rule are Eye of Skadi + a Lifesteal type orb or Searing Arrow, which work together at the same time | |
1 | These only count as orb only on the attack they proc, and will not override other orb otherwise |
