baron, peerage, court rank
爵 centers on noble rank and hereditary title, specifically the rank of baron within a peerage system. The given meanings all relate to this concept of aristocratic court rank.
爵 originally depicted a ritual wine vessel used in ancient ceremonies, which later came to symbolize the rank of the person who used it. The modern form retains the top 爫 (claw/hand) and lower elements that are remnants of the vessel shape.
The top 爫 looks like a hand holding a ceremonial wine cup (the lower part 罒 and 寸 suggest a vessel). Imagine a noble baron raising this cup at court to show his rank.
For シャク, imagine a baron being given a ceremonial cup that is a bit shaky in his hands: shaky -> シャク, and the shaky cup represents his noble rank.
