I remember there is a problem with the "menuselect n" client commands in CS 1.6. It's not your fault; it's a CS bug. To make sure bots buy effectively what you tell them to buy you should make them buy using the new shortcuts (like "famas", "deagle", etc.) For this I advise you to change a bit your bot_weapon_select_t structure and change these

int iNewBuySelectT;
int iNewBuySelectCT;

into a char array where you will put the buy shortcut to use for each weapon. For example:

char buy_shortcut[32];

You can then replace

FakeClientCommand(pEdict, "menuselect",szMenuSelect, NULL);

with

FakeClientCommand(pEdict, pBot->pSelected_weapon->buy_shortcut, NULL, NULL);
