You can first try to undeclare the definition of \d{s} and so try
out if the font has an combining accent:

\documentclass{article}
\usepackage{fontspec}
\setmainfont[Mapping=tex-text]{Minion Pro}
\UndeclareUTFcomposite{x1E63}{\d}{s} %first try

\begin{document}

Āāīūś  % works as expected.
ṣṇṭḍṃḥ % just crossed out boxes.

\d{s} %Does it work?

\end{document} 

But normally a font that doesn't have ṣ hasn't the dot accent
either, so you will probably see an "s with a crossed box".

Then you could define a default definition like the one OT1-encoding
uses:

\documentclass{article}
\usepackage{fontspec}
\setmainfont[Mapping=tex-text]{Minion Pro}

\makeatletter
\DeclareTextCommand{\d}{\UTFencname}[1]
   {\hmode at bgroup
\o at lign{\relax#1\crcr\hidewidth\ltx at sh@ft{-1ex}.\hidewidth}\egroup}
\catcode`\ṣ=\active
\defṣ{\d{s}}
\makeatother

\begin{document}

Āāīūś  % works as expected.
ṣṇṭḍṃḥ % just crossed out boxes.

\d{s}

\end{document}


It will look ok, but won't copy and paste correctly.
