Sanjoy,
the following borrows the \pm sign from Asana (which also should be
like palatino), which looks more "normal".
% Start example
\definefallbackfamily[mainface][math][Asana Math]
[range={00B1-00B1}]
\definefontfamily[mainface][serif][Tex Gyre Pagella]
\definefontfamily[mainface][math][Tex Gyre Pagella Math]
\starttext
\switchtobodyfont[pagella] Hello $\int x \pm 2 + a $\par
\switchtobodyfont[asana] Hello $\int x \pm 2 + a $\par
\switchtobodyfont[mainface] Hello $\int x \pm 2 + a $\par
\stoptext
% Stop example
I guess one could do this for the other signs one don't like in TeX
Gyre Pagella Math...
/Mikael
