I don't know about the timeline of Vimscript in particular, but seemingly Vim was first released in 1991 while Lua first 1993, so by the first release of Lua, Vim already existed by then. Not sure when Vimscript appeared though. On other trends (Google Trends to be specific), search volume for Lua only became larger than for Vim in 2004, with Lua hitting it's peak in 2009. Search volume for Vim would have been much larger before 2004 if we had a single search engine everyone could have used, but hard to know in afterhand I guess.
