I have bought Charlie Chan scripts on eBay for amounts ranging between about $250 - $300. If your script was used, and perhaps signed, by Joan Valerie, who played Lili Latimer in the movie, the value could be somewhat more.
If you are a fan of Charlie Chan, my suggestion would be that you keep the script, treasure and enjoy it, and, most importantly, preserve it as a valuable historic document.
I have boxes and boxes of things from my diseased aunt's estate and just started to go through them, pulling out things that appear to have value to cover her estates bills.
I am not a movie fan of any kind, so they have no fan value to me.
Yes, the script is signed and I have a Charlie Chan pictures with Ms. Valerie. Looks like a publicity picture that was handed out during that time period, but it is unsigned.
