Formula/Macro help needed please

I have a spreadsheet that will contain around 50 rows and 25 columns and a sample is attached.
I already have top/bottom rules set by conditional formatting. This colour fills the top 12 value cells of each column and gives a total value of those cells.
What I also would like to do is to be able to sort each column in numerical order but can only do this by sort each column individually which is slow.
Any suggestions how I may achieve this in an easier way.

The end result should give me a total for each of the 12 highest values in each column and also indicate which is the lowest counting value in each column. (See Colums B-G)

Thank you for reading this
