It would help if you posted the code that generates the cell array you want to sort.

You can try this out.

B = {[5,6] [1,2] [5,8]};
[~,i] = sort(cellfun(@(x)sum(x.*power(10,[length(x):-1:1]-1)),B));
B = B(i)
B = 1×3 cell array
    {[1 2]}    {[5 6]}    {[5 8]}

This is just converting the array into a decimal value so [5,6] to 56. So makes it easier to sort the numbers. Though you can replace it with the maximum value you expect to be present in your array and it should still work well enough.

B = {[5,6] [1,2] [5,8]};
cellfun(@(x)sum(x.*power(10,[length(x):-1:1]-1)),B)
ans = 1×3
    56    12    58
