KOMA doesn't have a size13.clo, it uses a fallback calculation:

Class scrartcl Warning: Using fallback calculation to setup font
sizes for basic size `13pt' on input line 1209.

But you can naturally generate a size13.clo (use size12 and size14
as examples). Then you can use extsizes to load it:

\makeatletter
\renewcommand\@ptsize{13}
\makeatother
\usepackage{extsizes}

(the main use of extsizes here is that you can avoid errors because
of the \newcommand's)
