To do so, I use the command \DeclareMathAlphabet{\zcit}{T1}{pzc}{m}{it}. This produces the desired A, but the symbol is too small and I would like to increase its size to match that of the symbol obtained with \mathcal(A).

This bypasses a problem that can occur with pzc when used in latex+dvips+ps2pdf mode, and download base 35 was not set to True. In this case, pzc renders from the faulty font distributed by Artifex in the gs distribution. (It is supposed to be fixed in gs 9.05.)

That should have been
\usepackage[cal=zapfc,calscaled=1.15]{mathalfa}

I should have added that this provides a math alphabet with proper math metrics so that accents and subscripts are where you expect them, and spacing in formulas is math-like rather than text-like.
