To run one map use this command: 

map q3dm1    ( I think)

OR 

set d1 "map q3dm1 ; set nextmap vstr d1"
vstr d1
 

To run a bunch of maps use this: 

set d1 "map q3dm1 ; set nextmap vstr d2"
set d2 "map q3dm5 ; set nextmap vstr d3"
set d3 "map q3dm7 ; set nextmap vstr d1"
vstr d1

In this case dont forget to set the last map to call the first map. 

In all cases below, settings must be entered before the map change command!
Let's say you want to change the timelimit and fraglimit for each map:

set d1 "fraglimit 30; timelimit 10; map q3dm1 ; set nextmap vstr d1"
set d2 "fraglimit 20; timelimit 15; map q3dm3 ; set nextmap vstr d2"
set d3 "fraglimit 40; timelimit 20; map q3dm5 ; set nextmap vstr d3"
set d4 "fraglimit 40; map q3dm7 ; set nextmap vstr d4"
set d5 "timelimit 20; map q3dm9 ; set nextmap vstr d5"
vstr d1

You can also change the gametype if you want to rotate FFA and Team DM:

set d1 "g_gametype 0; map q3dm7 ; set nextmap vstr d2"
set d2 "g_gametype 3; devmap q3tourney1 ; set nextmap vstr d3"
set d3 "fraglimit 30; timelimit 15; g_gametype 0; map q3dm4 ; set nextmap vstr d1"
vstr d1

But if you change the gametype, don't forget to set it back or all the next maps will have the same game type too! 

You can also set the message of the day for each map if you want to liven things up.
The vstr d1 command must appear after the last map selection.
