Ruby Greed Koan – 如何改善我的汤匙？

在下面的代码中,有没有办法让我更充分地拥抱Ruby模式？ (我的代码包裹在“我的代码[开始|结束]在这里”评论.

# Greed is a dice game where you roll up to five dice to accumulate
# points.  The following "score" function will be used calculate the
# score of a single roll of the dice.
#
# A greed roll is scored as follows:
#
# * A set of three ones is 1000 points
#
# * A set of three numbers (other than ones) is worth 100 times the
#   number. (e.g. three fives is 500 points).
#
# * A one (that is not part of a set of three) is worth 100 points.
#
# * A five (that is not part of a set of three) is worth 50 points.
#
# * Everything else is worth 0 points.
#
#
# Examples:
#
# score([1,1,5,1]) => 1150 points
# score([2,3,4,6,2]) => 0 points
# score([3,3]) => 350 points
# score([1,2,4]) => 250 points
#
# More scoring examples are given in the tests below:
#
# Your goal is to write the score method.

# MY CODE BEGINS HERE

def score(dice)

  # set up basic vars to handle total points and count of each number
  total = 0
  count = [0,0]

  # for each die,make sure we've counted how many occurrencess there are
  dice.each do |die|
    count[ die - 1 ] += 1
  end

  # iterate over each,and handle points for singles and triples
  count.each_with_index do |count,index|
    if count == 3
      total = doTriples( index + 1,total )
    elsif count < 3
      total = doSingles( index + 1,count,total )
    elsif count > 3
      total = doTriples( index + 1,total )
      total = doSingles( index + 1,count % 3,total )
    end
  end

  # return the new point total
  total

end

def doTriples( number,total )
  if number == 1
    total += 1000
  else
    total += ( number ) * 100
  end
  total
end

def doSingles( number,total )
  if number == 1
    total += ( 100 * count )
  elsif number == 5
    total += ( 50 * count )
  end
  total
end

  def test_score_of_an_empty_list_is_zero
    assert_equal 0,score([])

    assert_equal 100,score([1])
  end

    assert_equal 300,score([1,1])
  end

    assert_equal 0,score([2,6])
  end

    assert_equal 1000,1])
  end

    assert_equal 300,score([3,3])

    assert_equal 500,score([5,5])
    assert_equal 600,score([6,6])
  end

非常感谢任何可以给我的帮助,因为我试图让我的头围绕Ruby.
