This answer shamelessly bundles the solutions others have found. I've contributed only the last missing answer and the meta answer. Definitions are in italics, solutions and wordplay in all caps.
- Stiff butt inside capital punishment, initially (5)
CRAMP – stiff; RAM (butt) inside CP (initial letters of capital punishment); found by TwoBitOperation
- Blinded tin turned ton with ocean sound (6, 3)
CANNOT SEE – blinded; CAN (tin) + TON< + SEA (homophone of sea)
- Drink for Eastern victory (4)
WINE – drink; WIN (victory) + E (Eastern); found by Sid
- Confused trope in pry land (8)
PROPERTY – land; anagram (confused) of TROPE in PRY; found by Chris Cudmore
- Playing E triad causes tantrum (6)
TIRADE – tantrum; anagram (playing) of E TRIAD; found by Sid
This yields the final clue:
Cramp cannot see wine property tirade (7)
The solution to that meta clue is:
RAMPAGE – tirade; [c]RAMP (cramp without C, "cannot see") + AGE (a property of wines as in "a 2012 Pinot Noir")
Thanks to all who have contributed partial answers!
