Strange thing: when i choose in 1bash for example ZEN or ZEC and ALGO_SPECIFIC_OC="YES", after miner restart settings from this algo are applied:

# Skunk
  if [ $COIN == "SIGT" -o $COIN == "ZPOOL_SKUNK" -o $COIN == "ALTCOM" ]
  then
    ALGORITHM="SKUNK"
    POWERLIMIT_WATTS=78
    __CORE_OVERCLOCK=150
    MEMORY_OVERCLOCK=1000
  fi
