Vielen Dank für die Erklärung!
Bezüglich deines Tipps über das Umdefinieren des Makros "cite" hätte ich noch ein paar Fragen. Ich habe mir jetzt mal die Datei "authoryear.cbx" angesehen und versucht herauszufinden, wie ich deinen Vorschlag umsetzen könnte.

Das Makro "cite" wird hier wie folgt definiert:
\newbibmacro*{cite}{%
\iffieldundef{shorthand}
{\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
{\usebibmacro{cite:label}%
\setunit{\addspace}}
{\printnames{labelname}%
\setunit{\nameyeardelim}}%
\usebibmacro{cite:labelyear+extrayear}}
{\usebibmacro{cite:shorthand}}}
Es setzt sich also aus folgenden drei Teilen zusammen, die ineinander verschachtelt sind:
\newbibmacro*{name}[arguments][option]{definition}\iffieldundef{field}{true}{false}\ifthenelse{tests}{true}{false}
Würde es also reichen, wenn ich das bestehende "\ifthenelse{...}{...}{...}" in die Operationsanweisung "true" eines weiteren "\iffieldundef{Number}{...}{...}" packe und mit der Operationsanweisung "false" dann "\usebibmacro{dincite}" aufrufe?
\newbibmacro*{cite}[arguments][option]{\iffieldundef{shorthand}{\iffieldundef{number}{\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}{true}{false}}{\usebibmacro{dincite}}}{false}}
