Why not something like this:

Spoiler

#pragma semicolon 1
#include <sdktools>

#define PLUGIN_VERSION "1.1.0"

public Plugin:myinfo =
{
    name = "Trigger_Push Fix",
    author = "iEx, Mitch",
    description = "Fix bug with trigger_push at touch",
    version = PLUGIN_VERSION,
    url = "https://forums.alliedmods.net/showthread.php?t=246423"
};

public OnPluginStart()
{
	HookEntityOutput("trigger_push","OnStartTouch",OnStartTouch);
}

public OnStartTouch(const String:output[], caller, activator, Float:delay)
{
	if(!(1<=activator<= MaxClients ) || (caller == -1) || (!IsClientInGame(activator)) || !IsPlayerAlive(activator))
		return;
	decl Float:Pushfix[3];
	GetClientAbsOrigin(activator, Pushfix);
	Pushfix[2] += 1.0;
	TeleportEntity(activator, Pushfix, NULL_VECTOR, NULL_VECTOR);
	return;
}
