I'm probably way off here but are you certain that the command line processing isn't interferring here?

Using your exact script on my win32 system, typing: 

C:\test>178232.pl "QUICK=BROWN FOX" "JUMPED=OVER THE LAZY" DOG
QUICK,JUMPED

[download]

Of course, the brain-dead CMD required me to quote the parameters with spaces, but the fact that it then works could mean that its your CLP that is interfering here.

Try inserting: 

local($,=",",$\="\n");    # << Corrected typo/brain fade
print @ARGV;

[download]

at the top of your prog and see what your getting in?

BTW. Is there any specific reason you are escaping the "=" with backslashes? Your regex seems to work fine without them.

update: correct minor typo. (And again!) Ditto!.
