I briefly closed this question, then realized I had more to say than easily fits into the comments.

This is documented behavior so in a way you have to learn to live with it, but the work-around is very simple: use SortBy

SortBy[{13, Sqrt[157], Sqrt[163]}, N]
{Sqrt[157], Sqrt[163], 13}

This is far superior to using Sort with a second argument as it preserves the lower algorithmic complexity of the default sort rather than the pairwise comparison that is used with custom ordering functions.

You can improve performance somewhat further if you are interested in only numeric order, or more specifically the default ordering of expressions as converted by N. This is done by using {N} as the second argument of SortBy which results in a stable sortstable sort. When using N (bare, without {}) ties will be broken using the default ordering function on the original expression.
