Well, not fully complete - missing 3 and 6, maybe I'll update those later (I have to actually work now). Here are my attempts.
First time golfing :-)

Hole #1 (score 10): sub b{(split)[4]}
Hole #2 (score 21):
perl -e'

goto TPC
'
Hole #4 (score 47): sub b{$_=reverse;push@_,chr(hex(chop.chop))while$_;@_}
Hole #5 (score 32): sub b{$t=pop;for(@_){$t=$_ if$_>$t}$t}
Update: Thanks tilly, I would never have noticed hole 5 - though I had some bad feelings about it. I don't know WHAT I was thinking for #1 :-)
update2: changed 5 to a working one now :-)
