With a fixed-width column containing the enumeration, the following is a possibility:

\documentclass{article}
\newcommand{\myitem}{\par\refstepcounter{enumi}\theenumi.\ }
\begin{document}
\centering
\begin{tabular}{rp{0.5\linewidth}}
Some\textunderscore text &
\myitem Other text
\myitem Other text
\end{tabular}
\end{document}
If you wish to have a different kind of enumeration display, adjust \myitem
to your liking. For example,
\newcommand{\myitem}{\par\refstepcounter{enumi}(\theenumi)\ }
provides brakcets around the numbering. The width of the second column is still an issue (whether it's sufficient or bad, say), but there's not much more one can do with the amount of detail available in the question.
