As you can see in the following simple example (the last item is commented out -- more on that soon), LaTeX pushes the baseline of the equation well below the baseline of the bullet. If I wrap the displayed equation environment in a \raisebox and raise it zero length, the baselines align perfectly.

I don't know the answer to your question, but the following workaround may be close enough.

\documentclass[12pt,fleqn]{amsart}
%\usepackage{amsmath}
\makeatletter
\def\tagform@#1{\maketag@@@{\ignorespaces#1\unskip\@@italiccorr}}
\makeatother

\begin{document}


\[
y = \int \sin x \,dx + x^{2}\tag{$\bullet$}
\]

\begin{align*}
y &= \int \sin x \,dx \tag{$\bullet$}\\
&\qquad{} + x^{2}
\end{align*}


\end{document}
