What does Linq .orderby for arrays do if there are two equal values in the array?

Hi there, just wondering if anyone knows this. What would

players = players.OrderBy(item => item.userVariables.Score).ToArray();

do to an array of four objects, if two of the items in the array were of equal value? would it return null?

thanks.

It will return the sorted array, with the two equal values in their original position respective to each other.
