How about a hash or something like that?

dir = ARGV[0]
store = Hash.new

Dir.foreach(dir) do |file|
  unless file =~ /^\./
    num, name, ext = file.scan(/([0-9]+\-[0-9]+)\ ([A-Za-z0-9\
]+)(\.mp3)/).flatten
    if store[name]
      store[name][:numbers] << num
    else
      store[name] = { :extension => ext, :numbers => [num] }
    end
  end
end

store.each do |name, properties|
  filename = name + properties[:extension]
  complete_file = File.open(filename, "w")
  store[name][:numbers].each do |num|
    part_filename = num + " " + name + properties[:extension]
    File.open(dir+"/"+part_filename, "r") do |f|
      complete_file.write(f.read)
    end
  end
  complete_file.close
end
