How about this:

SQL

DECLARE @mon VARCHAR(32) = 'sep-14'
PRINT DATEPART(m , CONVERT(date, '1-' + @mon , 6))

And please don't store dates as strings.

I am not going into detail of your table schema because you know the best design for your data. But I would not store the date as string in first place.

Anyway, you could do some string manipulation and have a query something like this:

SQL

SELECT
    SUBSTRING (Months, 0 , 4) AS Month,
    CONVERT(INT, SUBSTRING (Months, 5 , 9)) AS Year,
    Month(SUBSTRING (Months, 0 , 4) + ' 12 2014') AS MonthNumber
FROM
    CP
ORDER BY
    Year DESC, MonthNumber DESC

After this you can use MAX, TOP etc. to what you want!
