sed,paste,grep,cut - 109

sed -e 's/[sc]h/6/g;s/[aehiouwxy]//g;y/sztdnmrljkcqgfvpb/00112345677778899/' w|paste w -|grep " $1$"|cut -f1

Takes a file "w", converts each word to its number, paste back to the original, grep for the number and return the word matched. Note that the whitespace after the quote after grep is a tab, paste's default delimiter.

I know Perl is way ahead, just wanted a better shell version as an example.

Oh yeah, the $1 part means that this is supposed to be run from a shell script, (most shells should work), so it takes a command-line argument.
