A few ideas on Sort:

age = {30, 12, 60, 20};
names = {"john", "kate", "peter", "alice"};
{age, names} // Sort
{age, names} // Sort // Transpose
Sort[{age, names} // Transpose, #1[[1]] < #2[[1]] &]
Sort[{age, names} // Transpose, #1[[1]] > #2[[1]] &]
Sort[{age, names} // Transpose, #1[[2]] < #2[[2]] &]
Sort[{age, names} // Transpose, #1[[2]] > #2[[2]] &]
Sort[{age, names} // Transpose, #1[[1]] < #2[[1]] &] // Transpose
Sort[{age, names} // Transpose, #1[[1]] > #2[[1]] &] // Transpose
Sort[{age, names} // Transpose, #1[[2]] < #2[[2]] &] // Transpose
Sort[{age, names} // Transpose, #1[[2]] > #2[[2]] &] // Transpose

Hi
How to sort two lists such as:
age={30,12,60,20};
pple={"john","kate","peter","alice"};

to give the output:
age={12,20,30,60}
pple={"kate","alice","john","peter"}

ie: to keep every person opposite his age number.
thanks
