```Note that OP constructed his list so that some values are weighted according
to the user's decision (Aggressive or defensive), Just let's not forget that
brilliance~ ;-)

This is one situation where the python concept of ask forgiveness later is
convenient.
For example.

###########
def play():
score = [1,2,3,4,6,'Out']
totalScore = 0
while 1:
hit = random.choice(score)
try:
totalScore += int(hit)
print "You batted a  %s; Total runs: %d" % (hit,totalScore)
except ValueError:
print "You're OUT! Total runs:", totalScore
break
############

And a way that is even better of which I just thought ;-)
Use a special value to mean 'out'. This avoids the string problem.
A value of zero makes the comparisons with if even simpler.

#########
def play():
scores = [1,1,2,2,3,4,6,0,0]  #Zero means "out"
totalScore = 0
while 1:
hit = random.choice(scores)
totalScore += hit
if hit:       # The magic check - even makes sense, if no hit, then
"out"
print "You batted a %d, Total runs: %d" % (hit, totalScore)
else:
print "You're OUT! Total runs: %d" % totalScore
##########

A sneaky application of a form of encapsulation that OOP people like to use.
;-)
(So you only have to have one play function)

#######
aggr_scores = [1,2,3,4,4,6,6,0,0,0]
defe_scores = [1,1,1,2,2,3,4,6,0,0]

user_choice = raw_input("Which?\n\t(a) Aggressive\n\t(b) Defensive\n\nYour
choice: ")
if user_choice == 'a':
scores = aggr_scores
elif user_choice == 'b':
scores = defe_scores
else:
print "Please choose a or b"

play()
########

Or even better.

#########
score_lookup = {'a':[1,2,3,4,4,6,6,0,0,0],
'b':[1,1,1,2,2,3,4,6,0,0]}

# raw_input here

scores = score_lookup[user_choice]
play()
