How to specify column alignment in LaTeX table output?

Here’s a table in my org document:

#+ATTR_LATEX: :align rrrr :options [htbp]
#+begin_table
|-------+--------+-----------+------------|
|  Tier | Number |     Total | % of Total |
|-------+--------+-----------+------------|
|     1 |      4 |  8,700.00 |      57.39 |
|     2 |     19 |  5,398.00 |      35.61 |
|     3 |     24 |  1,061.40 |       7.00 |
|-------+--------+-----------+------------|
| Total |     47 | 15,159.40 |     100.00 |
|-------+--------+-----------+------------|
#+end_table

I want all the columns to be right-aligned (as they are in the org document), but when exported to LaTeX/PDF, the “Total” column in the output table is left aligned instead. Here’s the relevant section of the .tex document generated during PDF export:

\begin{table}[htbp]
\begin{center}
\begin{tabular}{rrlr}
\hline
Tier & Number & Total & \% of Total\\
\hline
1 & 4 & 8,700.00 & 57.39\\
2 & 19 & 5,398.00 & 35.61\\
3 & 24 & 1,061.40 & 7.00\\
\hline
Total & 47 & 15,159.40 & 100.00\\
\hline
\end{tabular}

\end{center}
\end{table}

What am I missing? If relevant, org-version returns

Org mode version 9.8-pre (release_9.7.18-223-g7ef659 @ /Users/stanton/.emacs.d/straight/build/org/)

Thanks for any suggestions.
