Roger,
Thanks for the reply but the array you create there will contain the sorted keys, not sorted values.

    The perl built-in function keys will retrieve a list of hash keys, and the built-in function values will retrieve a list of hash values.
    sort keys %$namesref

# change keys to values to generate sorted list of values

sort values %$namesref
