I think the -50/-75 to movement was added because originally (RM2), movement was the only action (other than parrying at half OB) allowed when stunned. All other actions were forbidden.

It might also be helpful to note that the original description of the Stunned Maneuvering skill in RM Companion 2 specified a -10 penalty to the skill roll per cumulative round of stun. Companion 2 also (confusingly) had its own Static Action table which noted both the -10/round penalty and gave additional difficulty penalties for number of rounds of stun accrued. E.g. 2 rounds of stun made the base Static Action manuever a Hard (-10) check. I say this his confusing because these difficulty levels don't line up with the simple -10/round that is mentioned both in the verbal description of the skill and in this very chart I am referencing on p. 92 of Companion 2.

Actually, I want the orcs to be like World of Warcraft orcs.  Since they are like "real" orcs. (there are some differences between a real orc and a WoW orc.)

I hate to break it to you, but orcs aren't "real"

I'd like to translate the World of Warcraft RPG orc race from from D&D3e to Rolemaster (SS/FRP).  Should I try a one to one conversion?  Or should I get Underground Races first?  Then compare greater orcs with warcraft orcs?  I could use a little guidance.

In what ways do want them to differ from Orcs that are already presented in the main book or the Logroki in the Shadow World books?

Given that the Stun Removal skill explicitly lists modifiers for the number of stun rounds already, I would assume you are not supposed to also apply the maneuver penalty for being stunned. Also, the -50/-75 penalty for being stunned only applies to "movement and maneuvering", which I take as meaning actually moving around, not all "maneuvers" in the RM sense of skill checks. Most actions don't have a penalty because they are simply impossible while stunned; stun removal skill is of course an exception to that.
