Neil,

   In this case, I really wouldn't use a dictionary for storing the values.
Rather, I would have a structure like this (change the names appropriately):

public struct FruitInfo
{
   public string Fruit;
   public int[,] Values;
}

   Then, you would have instances of your structures that you create in an
array.

   Once you have all of these, you can call the static Sort method on the
Array class, passing a delegate to the comparison parameter to determine the
sort order:

// The array of FruitInfo instances.
FruitInfo[] fruitInfo = ...;

// Assume you have populated the array of fruitInfo instances.
Array.Sort(fruitInfo, delegate(FruitInfo x, FruitInfo y) { <code to do
comparison here> > });
