tabfigures and scrreprt: tabular figures in ToC

A MWE

documentclass{scrreprt}
usepackage[T1]{fontenc}
usepackage[utf8]{inputenc}

usepackage{MinionPro}
usepackage{universalis}

%usepackage[toc]{tabfigures}

begin{document}
setcounter{page}{73}

tableofcontents

chapter{This is the first chapter}
section{First section}
clearpage
section{Second section}
clearpage
section{Third section}

chapter{This is the second chapter}
Blabla.

end{document}

will produce:

I would like to have the proportional figures provided by MinionPro (chapter/section numbers as well as page numbers) vertically aligned: They should be typeset in tabular figures. The tabfigures package intends to achieve this. Uncommenting the line containing usepackage[toc]{tabfigures} above will give:

While the section figures are now properly aligned, tabfigures tries to patch the figures associated with chapters (which are typeset using the sans-serif font when using the scrreprt class) as well. The pdflatex log says:

(C:UsersmailAppDataRoamingMiKTeX2.9tex/latex/universalist1universalisad
fstd-lf.fd) (mwe.toc
No file T1UniversalisADFStd-TLF.fd.
No file T1UniversalisADFStdx.fd.

LaTeX Font Warning: Font shape `T1/UniversalisADFStd/b/n' undefined
(Font)              using `T1/cmr/m/n' instead on input line 1.

Here is what I get when using documentclass{book} along with usepackage[toc]{tabfigures}:

Looking good. book uses the roman font for displaying chapter titles. Using documentclass{scrreprt} with usepackage[toc]{tabfigures} and addtokomafont{chapterentry}{rmfamily} is a workaround where ToC chapter entries will be typeset in MinionPro while leaving chapter headings in the actual document in sans-serif letters. However, I would like to stick to the default style of scrreprt with chapters being sans-serif within the ToC AND the document itself. Is there a way to fix this behavior?
