First the pipe to wc is redundant.
Just use grep's count option -c instead.
e.g.
Code:
OrigNum[$aa]=$(grep -c ${Orig[$aa]} Ba3In2F12.prepos)

The syntax error is probably cause because your loop variable $aa
which acts as an array index has a leading zero.
Also remember that array indeces start counting from 0.
Try something like this instead (works for bash)
Code:
for ((i=0; i<${#Orig[*]}; i++)); do
     OrigNum[$i]=$(grep -c ${Orig[$i]} Ba3In2F12.prepos)
done

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
