Wildcard is evaluated by the operating system

But the operating system doesn't (logically) recognize the GDAL special 
/vsizip/ file system, so the wildcard is not evaluated.

A modest complementary development would have to be done to evaluate the 
wildcart inside gdaltindex.

An alternative might be to use the gdal_ls.py sample utility 
(http://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples/gdal_ls.py), 
redirect its output to a file and specify this file with --optfile to the 
gdaltindex command line.

python gdal_ls.py /vsizip/the_zip/the_subdir > filelist.txt
(you may need to filter non tif files. with the Windows equivalent of grep, or 
potentially the port of the unix grep : 
http://gnuwin32.sourceforge.net/packages/grep.htm)
gdaltindex the_index.shp --optfile filelist.txt
