Time-integrated and picosecond time-resolved excitonic luminescence of cation-substituted Zn$-x$/Cd$-1$MIN@x$/S (0 $LSEQ x $LSEQ 0.6) mixed crystals has been studied at T $EQ 1.8 K. It is shown that disorder-induced broadening - spread of exciton resonance energy due to alloying - is not the decisive factor that governs the widths (and shapes) of excitonic bands in time-integrated spectra. Emission transients are analyzed to clarify the relative importance of tunneling (usually associated with localization of excitons by disorder that is known to dominate in model anion-substituted CdSe$-x$/S$-1$MIN@x$/ system) versus binding by impurities. Tunneling in the range x $LSEQ 0.3 is ruled out whereas the indisputable evidences of it in temporal behavior are revealed for the samples with x $EQ 0.34 and x $EQ 0.41 though on substantially shorter timescale than in CdSe$-x$/S$-1$MIN@x$/. It is suggested that in cation-substituted Zn$-x$/Cd$-1$MIN@x$/S the broadened levels of impurity-bound excitons are involved in tunneling whereas the contribution from the disorder-induced fluctuations of crystal potential is less important than in anion-substituted CdSe$-x$/S$-1$MIN@x$/.
