I believe GtkSourceView is a subclass of GtkTextView. So it'd simply be:
gtk_text_view_set_tabs (GTK_TEXT_VIEW (yoursourceview), yourtabs);

However, this only sets the default tabs.

According to the documentation, you can create a tag, and set the "tabs"
and "tabs-set" properties on it:
http://developer.gnome.org/doc/API/2.0/gtk/GtkTextTag.html#GtkTextTag--tabs

Then just apply it to a region in the buffer.
