A Problem With Sorting via Applescript

Question

Hello everyone. I have always lurked these forums and learnt many things along the way, but this is my first question, and I hope that someone can help me out. I apologise for the huge post.
I have created a spreadsheet in Numbers that I plan to use for a soccer tournament. There are 8 Groups of 4 teams in the competition, so I have set each Group up on its own sheet in order to record the results of the games. Group 1 is on Sheet 1, Group 2 is on Sheet 2 etc. These results are then fed into a second table on the each page in order to create a competition ladder for each group. So far so good, works beautifully. See image:
My next step is sorting these tables so that they form a proper "results table" with the best team on top. My wish is to sort the results table in this order:
Points
Diff
F
Although not very experienced with Applescript, I have written a script to sort all of the 8 sheets so that I don't have to do them one at a time. Unfortunately I find that every second sheet does not sort correctly, even though I am using the same instructions for each seet in my script.
See here, sheet two:
Sheet 3 sorts correctly but not sheet 4, sheet 5 is good but sheet 6 bad etc...
This is my script:
tell application "Numbers"
          tell table "Ladder1" of sheet "Group1" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder1" of sheet "Group1" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder1" of sheet "Group1" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder2" of sheet "Group2" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder2" of sheet "Group2" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder2" of sheet "Group2" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder3" of sheet "Group3" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder3" of sheet "Group3" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder3" of sheet "Group3" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder4" of sheet "Group4" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder4" of sheet "Group4" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder4" of sheet "Group4" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder5" of sheet "Group5" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder5" of sheet "Group5" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder5" of sheet "Group5" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder6" of sheet "Group6" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder6" of sheet "Group6" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder6" of sheet "Group6" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder7" of sheet "Group7" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder7" of sheet "Group7" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder7" of sheet "Group7" of document "Manu"
  sort by column "g" direction descending
          end tell
          tell table "Ladder8" of sheet "Group8" of document "Manu"
  sort by column "k" direction descending
          end tell
          tell table "Ladder8" of sheet "Group8" of document "Manu"
  sort by column "i" direction descending
          end tell
          tell table "Ladder8" of sheet "Group8" of document "Manu"
  sort by column "g" direction descending
          end tell
end tell
Can anybody see any obvious errors with the script? Any info would be greatly appreciated. Thanks!

Answer 1

First I would look at some items to simplify the script:
I did NOT run this.
tell application "Numbers"
          set LadderNumber to 1
          repeat 8 times
       set theLadder to "Ladder" & LadderNumber
       set theGroup to "Group" & LadderNumber
       tell table theLadder of sheet theGroup of document "Manu"
            sort by column "k" direction descending
            sort by column "i" direction descending
            sort by column "g" direction descending
                         end tell
                         set LadderNumber to (LadderNumber + 1)
          end repeat
end tell
I don't see a problem with the script.  I suggest adding a dummy table to each sheet and confirming you can set a value in the dummy table from the script (maybe after manually setting the value to some default value).  you can also add print dialogs at each step to see what's happening... like:
set aValue to <what ever>
display dialog "The value is: " & aValue
just some thoughts
