Subject: comparison of Array with Array failed

I am passing this hash to a method to sort it, which works in irb but in
rails I can't get past it

report = {
  :cals => @total_cals,
  :fat => @dv_fat,
  :sfat => @dv_sfat,
  :carbs => @dv_carbs,
  :chol => @dv_chol,
  :sodium => @dv_sodium,
  :protein => @dv_protein,
  :fiber => @dv_fiber,
  :calcium => @dv_calcium,
  :copper => @dv_copper,
  :folid_acid => @dv_folid_acid,
  :iron => @dv_iron,
  :magnesium => @dv_magnesium,
  :iron => @dv_iron,
  :pantothenic_acid => @dv_pantothenic_acid,
  :phosphorus => @dv_phosphorus,
  :riboflavin => @dv_riboflavin,
  :thiamin => @dv_thiamin,
  :a_iu => @dv_a_iu,
  :b6 => @dv_b6,
  :b12 => @dv_b12,
  :c => @dv_c,
  :d => @dv_d,
  :e => @dv_e,
  :zinc => @dv_zinc,
  :potassium => @dv_potassium }


Here is the method giving me trouble

def overview_text(report_hash)

    array_sorted = report_hash.sort { |a,b| a[1] <=> b[1] }.reverse

    rich = very_plentiful = plentiful = good_source =
    small_amount = minimal_amount = Array.new

    @a = 0
    until @a == array_sorted.length
      if array_sorted[@a].last > 35 && (array_sorted[@a][0] == :fat or
array_sorted[@a][0] == :carbs or array_sorted[@a][0] == :protein or
array_sorted[@a][0] == :fiber or array_sorted[@a][0] == :chol)
        rich << array_sorted[@a].first.to_s
      elsif array_sorted[@a].last > 35 && (array_sorted[@a][0] != :fat
or array_sorted[@a][0] != :carbs or array_sorted[@a][0] != :protein or
array_sorted[@a][0] != :fiber or array_sorted[@a][0] != :chol)
        very_plentiful << array_sorted[@a].first.to_s
      elsif array_sorted[@a].last <= 35 && array_sorted[@a].last > 20
        plentiful << array_sorted[@a].first.to_s
      elsif array_sorted[@a].last <= 20 && array_sorted[@a].last > 8
        good_source << array_sorted[@a].first.to_s
      elsif array_sorted[@a].last <= 8 && array_sorted[@a].last > 2
        small_amount << array_sorted[@a].first.to_s
      elsif array_sorted[@a].last <= 2 && array_sorted[@a].last > 0
        minimal_amount << array_sorted[@a].first.to_s
      end
      @a += 1
    end
    output = "Rich in #{rich.to_sentence}, ",
             "Very Plentiful in #{very_plentiful.to_sentence}, ",
             "Plentiful of #{plentiful.to_sentence}, ",
             "a Good Source of #{good_source.to_sentence}, ",
             "with Small Amounts of #{small_amount.to_sentence}, ",
             "and Very Low in #{minimal_amount.to_sentence}."
.
