Humm… to use on a phone browser i highly doubt that is something like that, but I’m not entirely sure.
Close thing that comes to mind is setting up a stash on your PC with a scrapper for eroscripts, then accessing your stash through your phone and using it to search what you want, check this topic and comments if you’re interested in trying that out.
Otherwise there is just really the use of the search function by filtering tags and other parameters or just going directly to the portfolios of scripters you enjoy.
