How can I have a sorted set of rows of Integer -> UUID where the integer may exist many times?

If you need to repeat an integer as a column name, add entropy and use a BytesType column.  Pack your integer in big endian format, and append another random packed integer.  When you slice the columns, only unpack the first 8 bytes.  You still get the desired sorting this way, though on repeats it will sort by the random portion.
