Try this:
my_array.sort do |item1, item2|
first_1=item1.first
first_2=item2.first
regex = /\w*_\d*_(\w*)_(\d*)/
first_1 =~ regex
letters_1 = $1
numbers_1 = $2.to_i
first_2 =~ regex
letters_2 = $1
numbers_2 = $2.to_i
if letters_1 == letters_2
numbers_1 <=> numbers_2
else
letters_1 <=> letters_2
end
end
