Because nothing told the linker to follow that logical at the start.
The linker automatically searches STARLET.OLB and IMAGELIB.
it found SORTSHR first in image lab, then was redirected -->
confusion.
So either you have to explicitly tell the linker in through an  OPT
file entry to go pick up you private/old version sort-shr, or also
replace it in (a copy of) IMAGELIB and point the linker to that or
just setup a whole alternate version SYS$LIBRARY as Brian suggests.

fwiw, i would not fell too bad about providing a newer shareable to
run on an older system, but where do you stop? The newer sharable
probably insists on other, also newer, shareable like perhaps LIBRTL.
I haven't checked that for SORTSHR but you would have to check.
