On pourrait modifier le macro `date` :
\documentclass{article}
\usepackage[backend=biber,
style=verbose-ibid,
citetracker=context,
dateabbrev=false,
doi=false,
isbn=false,
url=false,
autopunct=false]{biblatex}
\renewbibmacro*{date}{%
\iffieldundef{origyear}{%
}{%
\printtext[brackets]{%
\printorigdate%
}%
\setunit{\addspace}%
}%
\printdate%
}
\begin{filecontents*}[overwrite]{\jobname.bib}
@book{test,
author = {Walter Ordsmith},
title = {An Old Work},
date = {2010},
edition = {5},
origdate = {1981},
}
@book{foo,
author = {Walter Ordsmith},
title = {An Old Work},
date = {2010},
edition = {5},
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
\autocite{test}
\autocite{foo}
\printbibliography
\end{document}
